We currently have a couple servers with Rackspace, and have been very happy with them, but are now looking for a slightly different service mix (and someone who doesn't charge monthly for RAM upgrades).
We need a high-performance, high-uptime host for a Win2K farm, and would like them to offer services for the day-to-day monitoring of our performance needs (not just canned services).
I stumbled across Datapipe, and after reviewing posts here they still look promising, but would appreciate any feedback on them as well as other vendors to consider. As you can probably tell, I'm far more sensitive to NOC quality/uptime and service level than pricing--as long as I'm using what I'm paying for. Not sure it matters, but we also tend to eat a lot of CPU but relatively little bandwidth.
