Yes, sorry! We're investigating, but my current theory is we got overloaded because I relaxed some of our anti-crawler protections a few days ago.
(The reason I did that is that the anti-crawler protections also unfortunately hit some legit users, and we don't want to block legit users. However, it seems that I turned the knobs down too far.)
In this case, though, we had a secondary failure: PagerDuty woke me up at 5:24am, I checked HN and it seemed fine, so I told PagerDuty the problem was resolved. But the problem wasn't resolved - at that point I was just sleeping through it.
I'll add more as we find out more, but it probably won't be till later this afternoon PST.

Which is fine! I don't mind if it's down for a few hours. It reminds me that it's just a place to stop by for a bit before moving on. Like a digital coffee shop that sometimes has a leaky pipe and isn't open right at 7am.
I hope it doesn't change (much).

We all have our moments, and I personally consider HN to be “best effort”, almost like a volunteer project. I’m not certain I’m correct: but thats the optics I have so my expectations are adjusted to that.
So don’t beat yourself up please.
When I worked for “SaaS unicorn” we typically had multiple levels of escalation, and acknowledging would have done nothing because the alarm would continue firing until fixed. Not sure what’s changed in 15 years of ops, I had assumed it would be better now- I can’t imagine silencing an alert totally by acknowledging it- if its still occurring.
I’m totally fine with how you handled it, if anything I am thankful. But that seems to be a system I would improve if I had the time.
“mute” is different than “resolve” to me, and both should exist. (Where mute is an acknowledgement of an issue as ongoing.)

This. If it were a business-critical money fountain, I'd expect follow-the-sun SRE coverage. I don't think it is, so I can probably accept drinking my morning coffee without scrolling HN once in a while. There's only so much one can beat oneself up about a slow/incorrect response when the on-call is handled by what, just one person? maybe two people in the same time zone?
(Might be wise though to have PagerDuty configured to re-alert if the outage persists.)

Though I will say, HN is a pretty great source of information about major outages like the recent AWS and Cloudflare issues. I had a moment this morning where I thought, oh, is there a larger issue and then, oh, HN is down, huh, the next option is so far down my list that it's going to take me a moment to think of it.
I hope that serves as a testament to how great this site and the community is. Thanks for all your hard work keeping it that way!

I was personally worried if there was some major outage of the whole world or something the first time hackernews didnt work because I didnt expect hackernews to go down but rather, something even more catastrophic than aws going down must happen (because we see major cloud outage posts)
https://downforeveryoneorjustme.com/hacker-news
This website had many instances of reports, the last I saw were 52 reports in only a short frame of time, the maximum reports on this are 118 it seems.
> In this case, though, we had a secondary failure: PagerDuty woke me up at 5:24am, I checked HN and it seemed fine, so I told PagerDuty the problem was resolved. But the problem wasn't resolved - at that point I was just sleeping through it.
Its okay I suppose, have you figured out who is crawling hackernews so much tho, was it a ddos attack or an AI company trying to get data, doesn't hackernews support an api and I am sure that there are datasets for it too so Its interesting why they might crawl but we all know the reasons why as they have been discussed here.

Maybe it would be fine if ops alerts were silenced during normal US sleeping hours?
HN is important, but unlikely much harm could be done before morning.

From dang's 2022 comment about traffic:
The most interesting number is the 1300 submissions because that hasn't grown since 2011 - it just fluctuates. Everything else has been growing more or less linearly for a long time, which is how we like it.
I find that surprising, as 2011-2022 covers an exponential rise in SEO spam and "growth hackers" attempting to drive traffic and links.
Or was 1,300 the number of non-flagged submissions?

The other reality is that as much as this industry is up its ass about scalability you can run a very very busy site on a single machine now a days.

Yes, sorry! This is the problem - we don't want to block legit users, but if we loosen the bolts, we get flooded.
If you browse HN while logged in, that should immunize you against this happening. Also, if it does happen again, you can unban your IP as described at https://news.ycombinator.com/newsfaq.html. But you have to do that from a different IP address, of course.
If those things don't work, email hn@ycombinator.com and we'll get it sorted.

Sometimes I could not open the comment section, receiving a blank page with "... We're sorry" or something along these lines when opening from new private window. It works when opening normally.
Logging in on the private window seems to resolve the issue. Can you take a look on this if possible?

In a situation like this one, good crisis leadership is essential. dang, HN will help you with tips from vast collected experience (please chip in):
1. Blame: The first thing to do is to point the finger. That doesn't mean analysing the technical issue, which can delay this step and limit your options, but figuring out who is politically easiest to blame. Often, that's the new guy, but outside contractors and vendors without good connections are also a common solution. Even if you are technically responsible for hiring them, you can always push them under the bus with a little skill. This small sacrifice helps unify, focus, and motivate the rest of the team.
2. Emotion: Inject your emotion into the situation and make that the implicit, but indisputable priority. Particularly, outrage and anger - This is completely _____. These people are utterly _____ (I'd use all caps, but that's not allowed on HN). Make sure everyone's attention is over their shoulder, on your emotion, and infect the team with it. Threats are an effective tool here - this is a crisis, and anyone who is calm is not emotionally engaged. Otherwise, they won't care enough about this problem - without you driving them, they probably wouldn't care much at all. Anyway, you don't have time for niceties like empathy or even basic respect.
3. Speed: Respnsiveness to stakeholders is very important. People need answers now. Give them answers they want to hear, outcomes they will be comfortable with. Don't worry if different groups hear different things. Your team will find a way to make it all work - that's their job.
4. Communication: Good communication is essential. Make sure you clearly tell your team what they should be doing; repeat it several times to prevent misunderstanding. Especially people with experience can have minds of their own; keep them on track. The situation is a crisis so you can't take any risks; stay on top of them and everything they do, and give input if you're not certain they are doing exactly what you would be doing.
5. Victimhood: Find a way to turn the tables: Make it about you, and how you're the victim here, and feed the fire with more outrage. With this and outrage, nobody will undermine the team by challenging your ideas or authority, which is the most essential component of a successful outcome. Remember, without you this all falls apart.

How does this happen?
Not the person you are asking. Bot operators have an incentive to make crawlers look as much like a human as possible so they do not get blocked. Some of them fail miserably and some nearly succeed. That makes it trivial to accidentally block a real person. I am personally fine with that given I do not pay for this site and have no SLA or contract with it.

There's a company in England called "Cascode" who make firefighter alerters. These are really basic "beeper" pagers, which you can program to have a bunch of different tones and LED patterns based on the RIC and Subcode.
I look after several thousand of these across several hundred paging sites.
They're relatively inexpensive (70 quid or so in quantity) and they last about six weeks on a commonly-available AA battery. The batteries go flat enough to trigger the "low battery" beep at about 3am, for some reason. I don't know why.
There's no messaging involved, although the encoders are capable of sending a text string. The message is "get up and get down to the fire station right now", which generally needs no further explanation. POCSAG is unencrypted, so there would be privacy concerns with sending actual incident information in the clear with it.
While we're on the subject of old tech, until BT finally cut the last of them off, we use dialup modems to control the encoders (not dialup internet, just a hundreds-of-miles serial cable) as a backup, and dot-matrix printers to print out a hardcopy message for the crews to pick up.
All very low-tech. All very fixable. All stays working if you don't mess with it.
