These guys do not have 24hr support.  They also have everything expire at midnight....and then they are not awake for 8 hours to fix an "oops".  Be careful if you have a server with extra IPs, whenever anything expires(or you don't want to renew) they will shutdown your entire server until they fix the "oops".  As for downtime, they had an internet connection(server was still up) out for an hour in the last 6 months, not too bad.  The support guy is Andrew Clarke...I shouldn't know that right?  LOL.
