I've had a dedi with ARP for about 4 years now, I think, and 0 hardware failures. fwiw. And I've gotta reiterate that nobody can promise 100% uptime (and anyone that does is either stupid, naieve, or both) But if your service can't withstand 2 minutes' downtime while your machine reboots, you've designed your service poorly because the fact of the matter is that sometimes shit happens, datacenters blow-up, humans unplug the wrong things, drive into transformers etc (not these things happened to ARP specifically, I'm just citing actual things that have happened to datacenters). The real point is that ARP does not make it a habit of rebooting customers' VMs (unlike a certain other VPS provider I won't name). Either it's planned host machine maintenance and they'll announce it (email, tweet, irc), or it's an emergency and they do what they have to do, but will announce it too. This is the best anyone can expect (or is promised) with any colo, and is better than what most shared hosting can promise. anyone have experience running email servers? I've got postfix/dovecot running but no mails sent to my domain are appearing and i'm not getting mails for undeliverable mail Check the logs? relay access denied is what its telling me sounds like postfix isn't configured to handle mail for that domain dump a sanitized "postconf -n" somewhere
