So one of my servers is down due to connectivity issues. Looks good from the console, no errors on the system log. I contact the host, the guy tells me to hard reboot the machine. I reply that this shouldn't be the case, but, hey, he's the expert, I assume.

I attempt a reboot and it can't boot because it can't connect to the network. The guy than tells me he will forward me to a tech person. THANKS A LOT.
