Update: An examination of the logs shows nothing remarkable happening at the moment of the crash.
We may have run out of some resource. In that case it may be hard to know for sure what happened.

Edit: this was using https, I didn't try http.
The reason it caught my attention was due to the recent https "Ask" threads, and my first thought was perhaps full time https had been implemented. I wouldn't bring it up except that it was unusual and correlated with HN content and the outage, even though it is likely to be a coincidence.
I didn't personally notice any http outage or delay.
"But there is no question that it is a good idea to get to the bottom of why this happened. I have found in the past it always pays to do a post-mortem on any system problem as many times there is something lurking that will cause that same problem in the future." [1]
I can't tell you how many times over the years some little thing has been an indicator of something else going on or caused a big problem later. It's normally better to diagnose this while you are not under duress, have room to breath, and aren't under any pressure.
[1] Non system related last week my wife couldn't get into the garage because the GFI on the same circuit as the garage door opener had tripped. The same GFI is in the upstairs bathroom and had blown previously many times but it didn't seem to be a problem. We didn't realize it also controlled the garage door. So she couldn't get into the house (she didn't have her key). So by ignoring the problem (just keep resetting the GFI and hey - figure it out later) we had a larger impact and issue than it seemed on the surface.
