I have been with Hostgator for 5 years, and have been content with them, up to now. I have a reseller account.
In recent weeks, their server disk’s keep getting full, which means that all my websites are down, and I and my customers can not receive any emails, because the physical disk is full (not over quota). Every time it happens, it takes HostGator a couple of hours to fix the issue. This is done by deleting some temporary files on the server, but then some days later the problem happens again. I told the support at Hostgator, that I would lookout for a new host, if this keeps happening, because I and my customers are potentially losing valuable business emails, that we do not receive while the issue persists.
This issue happened again today, and I am therefore now looking out for a new webhost, which offers reseller accounts. Can you recommend anyone?
It seems that you are under good protection now ;).
In any way I believe sometimes you need to move to a bigger solution. That is very important for you to understand that. After 5 years I believe that is something you need to do.
