Outage troubleshooting

  • If a load-balancer is out: see LVS
  • If errors on mw, look at the relevant hosts in ganglia, see if anything stands out, and look at the mediawiki error graphs.

In case of a persistent spike in fatals, look at the fatal log, which is currently at fluorine:/a/mw-log/fatal.log
