There was the standard 30min and 15min warnings; those were my first hints this was coming
Those assume you were actually on Tribble to see them, From ukcaptain's post I am taking it as he wasn't and only just recently tried to long on, only to fail (obviously) because Tribble had been taken down for maintenance.
So a curiosity question. How long are these maintenance sessions usually. I've failed to really notice in the past, are they usually a standard 2-3 hours ish, or do they vary, 30 mins to 5 hours for example.
