Re: Gitlab currently throwing a lot of 502s

23 Apr 2026

      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 http://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
