The data's *always* been safe. /r/DataHoarders would never overlook this.
Nvidia will serve you a free, high-speed half-terabyte download right now[0]. It's one with a cutoff date of 2020—but given that GPT-3 was released mid-2020, that's probably the one you actually want, for ML research.
Was it mentioned somewhere that they got compromised? And that it's not for example a hardware failure? I imagine lead times for getting brand new hardware would be in the 2–4 week range these days.
> Imagine if there was an API to rent servers within minutes or someday even seconds.
Imagine if everyone offering said API were capricious, inhumane, and uncaring about customer support, service terminations, and customer wind-down processes.
Now that you’ve pictured AWS, GCP, DigitalOcean, et al. more fully, that rules them out as available options for a long-term fanfic-centric erotica archive site that has specific and unusual legal concerns and threats to its existence incompatible with skittish Redbox-style compute providers.
Was there a particular cloud provider you were thinking of, that is not a ‘good night, sleep well, perhaps we’ll kill you in the morning’ service provider incompatible with AO3?
> There are a few "Nazi" hosting providers that could probably handle AO3.
I mean, you’re welcome to supply ammunition against your own argument here — ‘every hosting provider with a server-provisioning API is either capricious or Nazi-welcoming’ is a pretty damning condemnation of your own point! But .. if that’s not your intent, then I don’t really understand what point you’re trying to make in support of these APIs, and pithy sentence replies aren’t doing you any favors in conveying an interpretable opinion about AO3, server provisioning APIs and checks notes Nazis(?).
Are you suggesting that AO3 is akin to Nazi content? Are you suggesting that non-skittish hosting providers are uniformly also unprincipled? Are you equating erotica and fascism? I’d prefer to hear your explanation in your own words rather than be forced to infer bad faith participation here.
non-skittish hosting providers are uniformly also unprincipled
Yeah, this is what I'm saying (although absolute free speech is itself a principle). I wish it weren't so, but you're 99% right that the cloud isn't really usable for anything outside the Overton window, whether it's far left, far right, erotica, pro-suicide, extreme trolling, etc.
However if you're using Cloudflare you can "hide" your backend hosting provider and they usually won't kick you out because they don't take any reputation hit. So I still suspect a mainstream cloud (with good off-cloud backups) could work for AO3.
> Are you suggesting that AO3 is akin to Nazi content? Are you suggesting that non-skittish hosting providers are uniformly also unprincipled? Are you equating erotica and fascism? I’d prefer to hear your explanation in your own words rather than be forced to infer bad faith participation here.
I think the point they're trying to make is that "normal" hosting providers like AWS, Azure or Google won't accept AO3 as a customer in the first place or yeet them the day the first DMCA email arrives or some Evangelicals yap about furries and they realize what their customer is doing. "Nazi" hosters (aka wherever Gab, Truth Social et al are hosted) or your average cybercrime "bulletproof hoster" are being used to deal with a lot of bullshit, or they just pipe any complaints straight to /dev/null - and they are used to dealing with cyberattacks of all kinds as well because they are a very, very juicy target for anyone from antifascist activists over cybercriminals wanting to cash in on Trump's Truth Social privileges to other nations' secret services that might want to sow chaos by manipulating Trump's Truth Social feed.
So... AO3 is nowhere near Nazi crap in terms of content, but a very, very similar threat model (exhaustion of customer support goodwill).
My understanding is that (at least part of it is)the OTW has legal concerns over hosting fan works on somebody else’s computer. So they took the very reasonable step of hosting it on their own computer.
When the threat model is "a fire takes out the DC", sure. But "the servers are root-level compromised", whoops, that's worth rebuilding from scratch. No way to make sure whatever AI agent did the compromise didn't go and embed malware in some flash ROM.
You seem to be jumping to a lot of conclusions here. Who said anything about any server being compromised? Much less root-level compromised? And an AI agent being involved?
> You seem to be jumping to a lot of conclusions here.
There aren't that many scenarios which make a restoration time of weeks inevitable, even after taking into account the AO3 people are volunteers - given the large intersection between nerds and fanfiction or a loooot of furries working in IT, I'd assume you'll find the most competent people working on it, so I doubt the cause is incompetence.
They say the data is safe, which implies an offsite backup with a different architecture (or a managed provider). They said in the past they had a secondary site which they could switch over to if needed, which implies that the issue is not related to hardware or datacenter problems (e.g. your usual backhoe related issue or a physical destruction of the datacenter).
And that leaves only two options: a) a former staff member went fully rogue and everything needs to be rebuilt because everything might be backdoored, but there is no indication of that, or b) they got compromised really hard by one of the multitude of the vulnerabilities that cropped up the last days and chose to rebuild from scratch for a similar reason.
(And as far as I know AO3, like FFN, is limited to text and stuff like cover art, so the dataset should be small and easy enough to restore from a backup)
> There aren't that many scenarios which make a restoration time of weeks inevitable
IIRC everyone involved in restoring this is a volunteer doing this in a few free minutes here and there. I don't think they have any paid IT staff. In the first three months of 2026, the entire org (which is more than just Ao3) spent around $50K total for all costs, most of which is colocation/hardware expenses.
Point is that you can't extrapolate recovery times from the commercial sector to Ao3 recovery times.
2-4 weeks feels so absurd that I reread the alert twice thinking maybe they meant something different. Database problem into discovery of failed backups, perhaps?
It'll be interesting to see the postmortem. I don't know much about their infrastructure.
Earlier today, we detected evidence of a security incident on AO3. We are still in the early stages of response to this security incident and determining its scope. AO3 will remain down while we continue investigating and addressing what has been found so far. However, we want to make some things clear:
First, no AO3 data has been deleted. All your works, bookmarks, kudos, etc., are safe.
Second, while we currently don't believe that the user database was stolen, we are also unable to rule it out. The AO3 database contains account information that may include your username, email address, IP address, and a hashed version of your password.
We use industry-standard techniques for storing passwords in a scrambled form that cannot easily be reversed. Even so, no hashing method can fully protect a weak or reused password from being cracked. As a precaution, we recommend that you change your passwords on any other sites where you use the same password as on AO3.
AO3 does not collect real names, so none could be exposed. Additionally, our donor information is held in an entirely separate system and is never linked to AO3, so that data has also not been exposed.
We will update everyone as our investigation continues; we may be unable to respond to individual inquiries from users. Please keep an eye on our official outlets for updates. Our next update will be posted when we have further information available.
Our current expectation is that AO3 will be down for a minimum of two weeks; however, it could take up to four weeks. During that time, we may be able to bring the site back up in a degraded state, meaning that not all features will be available and/or the site may be read-only. If we are able to do that, please be aware that we might have to bring the site back down unexpectedly as part of our recovery efforts. We will keep you in the loop for any developments
Well that's annoying. I was literally planning later today to go through the list of active stories I'm following at Fanfiction.net, see which ones are also posted on AO3, and switch to reading those on AO3 because FFN is falling apart.
As someone who is just a reader the main annoyance at FFN is that when a story gets a new chapter it is often hard to get it to actually show the chapter. Sometimes you can only get it if you try to go directly to it, sometime you can only get it if you go to it from the previous chapter. Sometimes you can't get it at all.
Also sometimes if you try to reread the next-to-last chapter to remind yourself of context before reading the new chapter it say the next-to-last chapter was not found. As with the last chapter sometimes you can get it if you approach from the right direction.
Sometimes it is even the last several chapters that get temporarily lost this way.
So far this eventually has cleared up on a given story but sometimes it takes weeks.
From what I've seen authors mention there are also several issues with its support for authors making them as frustrated and annoyed as us pure readers.
Recently I've also noticed even the browsing story categories is falling apart. E.g., go there and from the "Browse" menu pick books. On the books page pick "Harry Potter". Then when it lists the HP stories click the "Crossovers" link to see the HP crossovers. That gives an error, and has done so for quite a while.
Funnily enough, I have scripts that archive my fandom's entire Tumblr, Ao3, and Fanfiction.net output. (The Tumblr one is an attempt, since you can't archive a fandom so much as the popular tags.)
There wasn't any bump in Tumblr creation timed to when Ao3 went down, and today the new season premiered, which triggers a huge bump on its own.
Per reddit [1] the data is safe.
Apparently they run bare metal that they own [2] so I'd assume their servers got compromised hard and they'll need to buy entirely new servers.

There are later dumps, but they aren't quite public

> And that it's not for example a hardware failure?
They say they have a second site, the chance of hardware failure taking out both sites at the exact same time is near zero.
As I understand it, the second site will allow them to resume operating at a limited capacity sooner than 2-4 weeks?
Other than that 2-4 does sound more like hardware lead time rather than time it takes to resolve a security incident.
Imagine if there was an API to rent servers within minutes or someday even seconds.

Their response is here and provides the desired clarification: https://news.ycombinator.com/item?id=50295919
Nazi hosting providers probably wouldn't be too cool with the bulk of Ao3's participants or content.
That speed comes with its own cost though. Might be simply too unreasonable at their scale.
My understanding is that (at least part of it is)the OTW has legal concerns over hosting fan works on somebody else’s computer. So they took the very reasonable step of hosting it on their own computer.

So much for that...

I too prefer reading on AO3 over FFN because AO3 allows me to export stories as epub so I can then read them on my eink reader. :-)
https://fichub.net/ Works well for exporting ff to epub. It works as a bookmarklet too.
Wonder if it's related to the Gitlab crisis (the regexp vulnerability in Ruby that hit them first). Ao3 seems to be a Ruby on Rails app.
