Hi,
I'm getting a lot of these errors today, having to reload almost everything I do on this forum. Is these a general issue ongoing please?
Thanks |

G3nt00,
I see it from Scotland from time to time too.
It began when the servers hosting the forums moved from one datacenter to another.
There is a theory that its due to 'crawlers'.

Crawlers? Load balancing? |

G3nt00,
Crawlers indexing the site. That's Google and others.
Also known as spiders.

More of these crawlers acting up today or what? It is great with the infra-status page, but would be even better with a bit of info on what's going on or why... |

Well, it's popping now again. I noticed a weird thing there too:
The error message comes with http 200 status code. Which would mean the errors are actually being indexed as the site's content. Should be either 503 or 429. If it's crawlers making server overload, perhaps 429 would slow them down a bit.
Maybe there is an easy way to replace the status code in those error responses? E.g. I've had a reverse proxy in front of apache limit number of simultaneous connections, queue the excess requests, and serve errors if they couldn't be dequeued in a timely fashion. (And a bunch of other things, like optimizing traffic for cache hits)
BTW, there's an easter egg in FGO's response headers  |

Wikipedia: Easter egg has as its top statement: | Code: | | This article is about items associated with Easter. For a secret message hidden in media, see Easter egg (media). |
That latter links to Wikipedia: Easter egg (media). Based on context, and the content of that page, it seems very likely this is what was meant. The specific Easter egg here is an otherwise meaningless HTTP header.
Similarly, working from context, FGO is likely Forums.Gentoo.Org, the domain on which we are having this discussion. |

Thanks Hu, I should have been more precise. I know what an Easter Egg is, I was more curious about the specific one mentioned. Though meaningless perhaps, it could be fun to know |
