error: 503 - 503 Backend fetch failed

Varnish cache server

is there some kind of ongoing problem? Or maybe something changed and I need to make changes in my code?

Best Regards

these can unfortunately happen sometimes, we get around 10% increase in traffic every month, scaling is a permanent challenge.

if you see these errors, it means our servers are struggling, we are notified, and work on it.

I believe it is fixed now, can you confirm @skoruppa ?
