Sorry you're having outage trouble, too. At least it confirms that I'm not going crazy.
I checked my web panel and it said that I had 100% uptime (day, week, and month) for all services on the domains in question. All of Sunday WAS taken into calculation in the statistic.
I've fired off a message to support asking them what gives and I'm really looking forward to a response.
I can deal with a hiccup in my service (although I've had other hiccups in the past), but to be told my my host that there have been no problems IS a problem.
