Hi Simon, 

since 12:00 we're getting another wave of spam. It's really hard to do something useful here, I will try more and more things but they will degrade UX for non-logged in users more and more. 

I'm prioritising UX for logged in users though. 

I'm unsure what to do to actually "solve" this issue. We're not seeing high traffic from singular IPs, we can't actually require log in for everything that people would like to do on the gitlab and gitlab itself is buggy in that it doesn't degrade well under load (now that I have fixed most of the other performance bottlenecks). 

I agree it's really frustrating and it's eating away at my personal time budget of working on actual GHC issues. 

Best 

Magnus

I'm still getting 20-second load times for individual pages (e.g. tickets) on gitlab.haskell.org.

Sometimes they errror out with "something went wrong, try again".

Are we stuck with what to do?  It's a bit frustrating.

Hello Devs,

just a short update and some background about Gitlab issues today.

Over the week and in particular today the number of requests to our
GitLab instance
has grown steadily, it now receiving way more than doubled the number of
requests it
received last week.

We have tried to solve this by adjusting some GitLab/server settings to
deal with this
(rate limits, checking for spammy IPs, the works) but with little
success so far since it
seems that the requests are pretty distributed across their origins.

Given it's not garbage requests but for valid endpoints we assume it's
"just" crawlers
(likely driven by the AI hype) indexing our instance. But while this
isn't a DoS attack
in it's totality the effect similar and it's unclear when we will make
progress on improving
the situation.

Magnus is working towards resolving this issue and we will let you know.

Cheers
Andreas
