No, not that I can see. There is a 'chart' of the stats showing green, yellow and red colors as to usage and it always has one of the disks at 83-85% (yellow) and the other one is not bad in the 30s (green). But the memory and server load fluctuate wildly sometimes going into red territory. That's usually means we can't get to TS. If things are in the yellow it usually just means things are slow.
Yesterday I had to repair the database at one point where one part had crashed. This was around 5 AM so probably no one noticed that TS was unreachable. Thing is, if this happens when Paddy or I aren't around TS could be offline for some time.
Once we get some more info we may contact ASO about possibly moving to another server but we're not sure that will be much better. Am looking into ways to trim our database which will make things a bit faster for us anyway.
