https://webapp0.softwareheritage.org/browse/search/ does not answer quickly when entering a new keyword for the first time.
Tried "danana" => got answers after more than one minute.
Also tried "zarg" => the wheel stopped spinning after one minute, with no explanation. A text message saying the pattern was not found could have been helpful.

I've got this error when searching 'github':

Error 503 Backend fetch failed

Backend fetch failed

Varnish cache server

Fixed multiple issues on that node's setup:

  • not using the right db for example [1]
  • missing postgresql setup regarding authentication (indexer service in dbreplica1)

It's now fixed.
And this seems to respond better, for example:

It now finishes.
It's still slow though.

I no longer see this behavior (hirsh/varnish is the cache in front of the proxy apache in front of gunicorn serving the django webservices).
