I haven't had any problems on a site I put at Infopop. I've only been there about 6 weeks so far, and have yet to see a problem, except with a few eve hiccups, and I'm not using that to any capacity at this moment in time. The page loads are snappy, and we are getting more service for less money than the previous host we were on. My Webhosting CP shows a server uptime of just under 40 days currently, and my Site Monitoring software hasn't beeped me yet for an outage.
A
NetCraft reading on my
personal site , shows a server uptime in excess of 400 days, which is hosted at Digital Princeton.
I've been on a budget host (PHP Webhosting) and my small UBB was just being murdered on their server with continual ISE's, even after migrating to a different server. They even tried blaming beta code at one point, and I told them that it was hogwash and pulled the site from them.
