We have successfully completed our migration to RAM-only VPN infrastructure
20 September 2023 NEWS SYSTEM TRANSPARENCY
Today we announce that we have completely removed all traces of disks being used by our VPN infrastructure!
In early 2022 we announced the beginning of our migration to using diskless infrastructure with our bootloader known as “stboot”. Completing the transition to diskless infrastructure
Our VPN infrastructure has since been audited with this configuration twice (2023, 2022), and all future audits of our VPN servers will focus solely on RAM-only deployments.
All of our VPN servers continue to use our custom and extensively slimmed down Linux kernel, where we follow the mainline branch of kernel development. This has allowed us to pull in the latest version so that we can stay up to date with new features and performance improvements, as well as tune and completely remove unnecessary bloat in the kernel.
The result is that the operating system that we boot, prior to being deployed weighs in at just over 200MB. When servers are rebooted or provisioned for the first time, we can be safe in the knowledge that we get a freshly built kernel, no traces of any log files, and a fully patched OS.
Mullvad is good, definitely my go-to VPN these days.
It’s a good day to be a Mullvad user. Switched over from Surfshark a while ago, and I love it.
no port forwarding. No business from me
Why not host your own on-site VPN server if you want to be able to dial in/allow others to dial in?
Still can’t torrent then
Is it noticeably faster than Surfshark for you?
You don’t use Mullvad for their performance, you use them for their insanely paranoid security and privacy practices.
And for the record, I was never impressed with Surfshark speeds. I dropped them when they bundled a virus scanner into their VPN client, that’s sketchy as hell. I don’t want my VPN provider scanning my files.
Mullvad has excellent performance though. I got nearly gigabit, I, unfortunately, had to switch when they removed port forwarding.
Yes I agree Surfshark has done some weird things. I find it weird that it’s actually the same company now as NordVPN, but they don’t make it clear.
Regarding performance, Surfshark is decent speed but still slower than not using a VPN. The more annoying thing is that I get a lot more captchas when using Surfshark. I think these issues are common for all VPNs, though I haven’t tried Mullvad yet (I will when my Surfshark subscription ends).
Yeah a lot of these little VPN companies are getting bought up by larger companies with unknown investors, it’s kinda worrying. There’s one company that owns ExpressVPN, PIA, and CyberGhost now: https://www.kape.com/our-brands/
Kape Technologies (previously named CrossRider) has a pretty sketchy history of making adware: https://www.forbes.com/sites/thomasbrewster/2015/06/09/from-israel-unit-8200-to-ad-men/?sh=7c46d70e26e2
I never had any real issues with speed using Surfshark, the reason I made the switch was largely about trust. As another user said, as soon as I saw Surfshark start their YouTube advertising spree, and start to bloat their client with unnecessary features, I started looking for alternatives.
I’m iffy about any VPN company that uses YouTuber marketing as it is, and while my threat model isn’t overly paranoid, I believe the VPN company someone chooses to use should have paranoid business practices. After I saw the news on Mullvad’s raid, the authorities subsequently finding nothing, and the fact that a user’s account is merely a string of numbers, I decided it was the VPN for me.
I haven’t noticed a difference but this company is significantly more trust worthy IMO
Funny thing is I started using Surfshark just before they started all the YouTube sponsorships. Them doing so many sponsorships actually made me trust them less somehow, if that makes sense.
Mullvad “appears” to be more trustworthy but maybe they are just better at marketing that image. They still cost twice as much as Surfshark.
The best piece of marketing Mullvad ever got was when the Swedish police raided them and Mullvad literally had zero data to turn over to them.
Usually when a company throws buckoos of money into advertisements, that’s where the money that could’ve been spent on a better product went. I’ve found products that were advertised so heavily, almost always have dog shit quality.
Mullvad compared to PIA, Google annoys me less with recaptures. I know it doesn’t answer your question but thought I’d throw my 2 cents in since PIA was quite a popular choice with their YouTube sponsor slots and cheap prices
It’s good to hear you get less captchas with Mullvad. At least for me, when using Surfshark + Private Browsing, I am basically guaranteed to get a ton of captchas on any Google searches.
Why is their logo a Mole when Mullvad is The Goat
In case someone actually ponders this, Mullvad means mole in Swedish.
VPN = tunnel
Nice.
Mullvad is such a good company. I just bought another month yesterday, but guess I’ll go and add another year to that!
Wow, that is very impressive. I’ve been a subscriber for a few years and I couldn’t be happier with their service.
Except with the removal of port forwarding
That didn’t effect me much personally and I could understand their reasoning. Still, it’s understandable that it lead to some frustration among other users.
I‘m not really informed on this. What is the reasoning to remove port forwarding?
Someone in this thread mentioned that was abused so much that hosting providers cancelled them. So they needed to remove it to be able to continue to operate.
I’ve been a subscriber for 5+ years and have zero issue with the loss of port forwarding. I use my devices for everything from gaming to torrenting, and haven’t run into something cause a problem that required me to use port forwarding on mullvad.
what has been an incredible source of frustration as a user of Mullvad tho is when websites block me or hit me with repeating captchas. I’ve also had a huge uptick of spam coming in from weird domains. Obviously not sure if thats mullvad-related, but sounds like the issue of “individuals have frequently used this feature to host undesirable content and malicious services from ports that are forwarded from our VPN servers”.
The removal of this feature seems to be a better of two difficult options.
Torrenting works better and faster with port forwarding.

I find the “Mullvad VPN scratch cards” interesting. If a store near you has them you could buy one and be totally anonymous. What I find a bit odd is that you can buy them on amazon as well but sold directly by mullvad. Doesn’t that defeat the purpose? The idea of the card is a decoupling of your real identity from the vpn user but when you buy the card in their store doesn’t it negate that?
I am probably just missing something here. Does anyone have more insight?
The code on the card is covered so Amazon might know you use Mullvad but they have no way of knowing what your account is.
Mullvad know your acct but they have no way of knowing how it is you paid other than maybe it being a scratchcard which they don’t track anyway.
I am not talking about amazon knowing it. Amazon offers shops for businesses, where a business directly sells goods to their customers using amazon as a transaction platform. Those shops send the goods directly to their customers (Sometimes it comes from an amazon warehouse as well tho). If the first case is true, mullvad would send me the card directly, so they would know I bought it, which makes the card obsolete in my view.
But maybe they don’t send it themself and the cards are all just sitting in a big warehouse. Either way, to me it’s not 100% a given that they couldn’t at least in theory know who bought it.
I am just playing devils advocate here btw, I am not really concerned about it.
You are buying access to a VPN not a nuclear warhead for the black market. The link between buying a VPN card and the code used in that card to link to said vpn activity which is also pretty well protected on Mullvad is not easily discoverable. Seems like a pretty reasonable privacy gap to me.
If you’re a Mullvad customer then they already know your IP and from that they could identify you pretty easily. But that’s true of all VPN providers, but they claim they don’t log and I seem to recall them saying they don’t keep a record of scratch off card numbers (why would they?). Either way you have to trust them and based on the fact they’re totally open I do.
Better yet, they employ a guy you can find in an alley who has a bunch of redemption cards in his trench coat. He takes cash or crack.
Removed by mod
Well amazon can tell youve bought a card
But not which code you recieved, on the physical card…
Just use cash.
Just use monero
Well the biggest selling point of VPNs is easier piracy not privacy. Most VPN customers just want to protect themselves from anyone watching their downloading habits. Yeah technically there would be a trail but no one is going to follow it to catch someone downloading inception.
Of only they’d kept port forwarding.
Didn’t really have a choice:
…Regrettably individuals have frequently used this feature to host undesirable content and malicious services from ports that are forwarded from our VPN servers. This has led to law enforcement contacting us, our IPs getting blacklisted, and hosting providers cancelling us.
Big issue there is hosting providers cancelling them. Can’t operate a business without that.
Short of getting their own servers of course. This update seems to be a step forward in that direction
Even if you own your own servers you still need somewhere to host them; ISPs / colocation providers are going to have the same issues with abuse.
They already own a lot of their own servers, or at least in the nordics.
Agreed. Seems like they were in a super tough spot with that and kind of had to drop it. All the sudden they seem to be doing some new cool stuff to try to keep their edge which I really appreciate / respect. That being said, I’ve dumped them and switched to a service that still port forwards as it gives me better torrenting throughput. Sorry Mullvad.
Only reason I switched away :(
From what I read in the article, there is still one part of the boot sequence that does require some sort of storage: the part where the bootloader fetches the network boot image and verifies it against the checksum signature. But I think that can be performed by booting from a pendrive and then removing it. The problem will come if law enforcement gets a hold of said pendrive…
Why would that be a problem? A boot image should only contain the commands to get the main system started after POST. It shouldn’t contain any kind of logs, traffic data, or user data. In fact it should be read-only.
Boot Drive could be immutable and not contain any form of log?
Destroy the drive. That’s what Apple does and how they get around the whole “we need a backdoor” problem. When no one can access the server, no more problems.
Something tells me that they have a stack of single-use drives so that each time a server needs to reboot for some reason, they write a boot loader in one from their central headquarters, walk back to the server room, use the device to boot the server, and finally hammer the everliving bejeezus out of the thumb drive juuuuust in case. Hopefully they don’t have to reboot that often!
What tells you that?
something
PXE boot will TFTP the boot image into RAM and carry on from there. You shouldn’t need any storage on your device.
Doesnt Matter, if the police wants the data, they come with Auto Batteries and an usp and make User of the multiple Power supplies of modern servers.
They will carry the whole rack in one piece if they can.
And if they don’t have anything recent in persistent RAM storage…?
How does this work? Surely they have backups on some kind of persistent media, right?
Interesting, will this affect performance at all?
I think (disclaimer: not an expert at all) that RAM is much faster to access than a hard drive so if anything it should improve.
It will make no difference to the performance of a VPN; nothing that those nodes are doing is IO bound.
Interesting what’s going happening with mullvad. For the best part of 10’years, you hear nothing.
Does anyone know why they are recently noisy?
Going by rate of blog posts by year they don’t seem any noisier than usual. The opposite if anything. 18 this year and there’s only 3 and a bit months left of the year whereas in 2018 they made 60.
You are incorrect. Look through their blog archive (scroll to the bottom): https://mullvad.net/en/blog/
They’ve been posting steadily for over a decade, maybe the posts just got more popular this year on whatever sites you browse
So now all that needs to happen is a freak solar flare or electrical surge to completely destroy their business?
I think you’re misunderstanding.
It’d turn the servers off obviously, but that’d be true if it was on disk or not. The source code is stored elsewhere probably on multiple data servers they access with git.
Not at all. Of course their operating system has to be booted from some kind of solid state disk, but all actual operations are carried out in the RAM, meaning that nothing is ever written to the disk. Since the RAM is periodically overwritten and doesn’t hold any data in case of a reboot or power failure, they are de-facto not logging a single thing.
I believe the edge devices would use netboot, so they load the kernel and user land into RAM over a network and have no disk in them at all.
Here’s hoping that image stays clean😉
Right, I mean that the boot image is stored somewhere in a solid state. Whether that’s on a centralized server or locally, no clue. But makes sense to load it remotely, easier to maintain proper versioning that way and ensure cross-compatibility.
Have they ever been audited like PIA?
The article is five very short paragraphs. The third one is:
Our VPN infrastructure has since been audited with this configuration twice (2023, 2022), and all future audits of our VPN servers will focus solely on RAM-only deployments.
Few times, yeah. Last time was August this year
Thank you, a real answer that compares to PIA
