I have been using Host Gator for my web hosting for over 4 years now and whilst it may not be the cheapest I have to say it is in my opinion the most reliable.
If you’re running a large site such as this one or many sites as I also do then you want the most sturdy web hosting you can get.
My main business website needs to be accessible al the time and so far I’ve had no problems.
Whenever I have ad problems they have been addressed within the hour.
Host Gator’s customer service in my experience has been second to none.
No matter what size your website is I recommend checking them out.
