I have been here since the end of December and came from a host who posted 99.9% uptime, yet their forums were constantly filled with complaints about being down, mySQL problems, really bad connections and speeds. I did some math and reviewed the webstats and it was more like a 78.8% uptime. I have had ONE problem since I have been here and it was only for 30 minutes (email problem). So just because it's posted isn't always the answer.
I like to compare it to this scene in a movei where the guy says "wheres the guarantee?" and the salesman says, "look, I could put a lump of crap in here, stamp it guaranteed and all you would have is a guaranteed lump of crap".
My point to all this rambling? So far so good here without the uptime posted anywhere. Very satisfied so far.
Cheers,
Wickie
