I'm looking at possibly putting a couple machines in with them, but have no experience with them. I've read a few threads with them mentioned here and there, but was hoping I could get some feedback on their services & support.
They are very nice people to work with - we use their Mzima bandwidth and have had no issues at all network wise. Support has been good, we've had reboots done quickly, etc. Were you looking at renting some servers or colo?
VERY highly recommended. I have had several servers with them and currently still do and no issues at all. The network is great. Sales responses may be a bit slow but only because they tend to do a lot of custom work.
