Screen short showing error
At least 4 users across 3 wikis are unable to login in most cases, getting error 503 from varnish in return of the login form. For each affected user, the issue is often browser- and/or wiki-specific: sometimes a user is unable to access an increasingly large number of wikis; sometimes bypassing caches helps. No other pattern was detected.
Asked for some multi-week grep -c for action=submitlogin&type=login 503 errors in logs, requires shell user.
When i try login in throogh Mozilla Fire fox i get error message sinc last 4 -5 days.
