I have a few sites with HostGator and they’re pretty good. I prefer to host my online casino and betting sites in either Canada or the UK though.
The sites in my sig are hosted as follows:
PresidentialSuiteCasino.com is with http://www.stormweb.ca who have the occasional problem but are reliable and on top of things.
Play-Online-Bingo.com is with http://www.gnhosting.co.uk/ – used to be Ghoulnet but have got their act together these days. An absolute bargain in my opinion.
Premiership Today.co.uk – that’s with HostGator. Lots of traffic and server processes running on this site and I’m very pleased with uptime etc.
