1. Yup, very fast. They colo with Hurricane Electric in their Fremont datacenter (using HE's bandwidth, of course).
2. Pretty good. I don't have any numbers for you, but the only network problem I've had worth mentioning (that I can remember) was discussed here. They also recently rebooted and changed the root pass, but it was an accident (wrong server). Luckily I had a back way in
3. Very good, except for one e-mail and phone call right after the previously mentioned incident.
4. No comment, I don't use it.
Sorry Csol, I've never used either of the other two hosts, and I prefer not to spread heresay You should do searches on all three here, and look in other places as well.
Just checked out @webhost. Their prices are very attractive -- P4 1.7GHz for $99/mo, full server management for only $125. But I've read that they had serious networking problems, and some people here at WHT were unhappy with them.
@webhost people post here on WHT and seem very responsive. Have they solved that problem with their network?
