I didn't keep count of the number of hours the AO servers have been down the past month, but it's totally out of line. A rough guess would be that we had at least 2 full days downtime the past 3 months. The cause of this downtime is that FC has to fix things up they screwed up in the first place, so I really think some kind of compensation would be more than welcome. Other MMORPG's I played compensated for downtime by adding a few days of gameplay to each account suffering the downtime.
Wednesday is my day off, and I barely get to play AO that day, I can perfectly live with a 1-2 hour downtime every week, but 4-8 hours is just too much, especially since the reason for the downtime is nearly always a fix for things FC messed up.
They don't even bother apologizing for their downtime anymore: "Greetings! All servers are now down for a client patch and server maintenance. Estimated downtime is 6 hours." Sounds like they even think it's normal to shut the servers down for 6 hours.
