At which time did you try about?
Yesterday evening up till early in the morning today,
SQL queries were
very slow. I did't take measurements but simple page queries that would
normally execute instantly would take minutes.
Did you try the whole night? Or which time? And which databases seemed to answer
slower?
The problem is that the head nodes are doing SQL forwarding too.
So if the active one is fishy you might not even have SQL connections.
But the phenomenon should have occured between about 0:30 and 1:30 am UTC (1:30 and 2:30
CET).
If you tried outside of this timeframe it would be good to know if you had any other
errors and what they looked like.
