Yeah that was one of the big reasons that I moved to
Colo-Cation. Other hosts that I have been on all had some kind of emergency power but often only for a short time until all the batteries went dead.
Colo-Cation has real diesel backups with guaranteed supple of diesel plus redundant data pipes so someone digging a ditch who cuts a cable doesn't knock the host down.
Two major hurricanes here and not even a few seconds down despite
Colo-Cation being located in Miami and much of Miami losing their power for many days.
Nothing worse then being down for even a short time and losing a lot of your traffic.
