As far as I know, cache.zw3rk.com is only semi-official, but it's been down for the past 3 days or so:

warning: error: unable to download 'https://cache.zw3rk.com/48l8knzjvx78z3g21n2bjrsz14aiksbr.narinfo': HTTP error 502

       response body:

       <head><title>502 Bad Gateway</title></head>
       <body>
       <center><h1>502 Bad Gateway</h1></center>
       <hr><center>nginx</center>
       </body>
       </html>; retrying in 258 ms

Is it coming back, or has it been retired?

I created a flake using the documentation and I'm currently experiencing the error

warning: error: unable to download 'https://hydra.iohk.io/hblxd27ml6q08m9rv43drzn6cp0wfana.narinfo': Timeout was reached (28); retrying in 526 ms
[0/1 built] querying haskell-project-plan-to-nix-pkgs on https://hydra.iohk.io

which might be related? Apologies if not, I'm not super familiar with that cache, but my suspicion is that the cache is 502-ing because the main site is down.

Looks like the substituters value changed in the documentation to https://cache.iog.io and I missed that from the last time I'd used this project. It might be related to the 502 you're experiencing, but updating my nix.conf fixed the issue for me.

@amy-keibler Use https://cache.iog.io instead

Yeah, we've been using cache.iog.io since August, but as far as I know, it doesn't include aarch64-darwin derivations, which cache.zw3rk.com does.

@dhess yea, that one query is in fact busted :(

this one on the other hand does work

I'll try to figure out what's going on there :-/ And yes it's the unofficial cache. It's populated from ci.zw3rk.com which has aarch64-darwin and aarch64-linux runners.

I think it's this one; aristanetworks/nix-serve-ng#19

@angerman Thanks, I'm glad it's just the one query (as far as we know), and not the cache having gone away :) It's very useful for us and I thank you for maintaining it.

I will close this issue as it's not really relevant to the project.

@dhess happy to help. I'll try to see if I can figure out what's broken with nix-serve-ng in this instance. It's already a massive improvement over the stock nix-serve (which kept timing out all the time with target stores 😱).

Possibly something similar happening again? The cache itself seems to be up, but some queries fail:

error: unable to download 'https://cache.zw3rk.com/8pjwr1y6pyqlkw7ws3hjgbg7576z5b9d.narinfo': HTTP error 502
