That's interesting... I have a mission-critical site (no pun intended, it's an evangelism site - missions - hahaha). We have a large international discussion forum - downtime is something I simply cannot have.
This is why I want to change servers. My current host backs up nightly at midnight eastern, which causes our west-coast users to be greatly inconvenienced - this is 9-10pm for them... primetime! We've lost traffic since being with this host. Then between 4-7am, the server bogs down - and they cannot tell me why. This affects US early-birds like myself and all of our Australian/NZ/Asian users.
So - I cannot have "routine" downtime with the site or email. Need resources. Need to be able to reach someone in case of trouble. If a server fritzes (and sure they will do so) I need it fixed or re-routed to another server pretty quick.
I've been talking with someone from DH for a couple of weeks now, explaining this mission-critical stuff - he's indicated that they can handle it. Is what I'm looking for too much for DH?
Thanks for your input I've just got to make sure we don't make a mistake a second time.
