Hey af0815,

The symptoms you are describing are usually the effect of a DDoS attack.

I'm not gonna bet money on that, cuz it could be some other technical issue, but it's usually a DDoS attack that saturates all the resources.

But again, I could be utterly wrong and it could be something trivial that will go away, or will be corrected by the very awesome(We don't praise our BOFHs ever enough) Ops person in charge :)

Cheers,
Gus

I've had to deal with rabid indexing bots in the past (including Google who deny it until you have a face-to-face meeting with them and show them the logs).

Oh, feel free to borrow :)

Yes, it was a DDoS. We've adjusted some settings to improve the situation, but in the end one simply has to weather it (it's not the first we had to).

Maybe someone got annoyed with our switch to GitLab? :-X

No, I think its probably the C++ community, they have just realized what a threat we are to C++
