So I just switched to a new VPS and have had some issues. I have setup a basic LAMP stack on Centos 6.2. I'm a programmer, but have a decent amount of knowledge in service administration since I work for a very small company and have to do a little bit of everything. I've setup many LAMP servers without any issues.
On this server, ever since I set it up the page load speeds have been ridiculous. On a basic Drupal 7 installation, page load times range from 10 sec to 60+ sec. As I was trying to get some work done earlier, the website just stopped loading altogether. I can't even access it via the IP address. But what's strange is that I can SSH into it via my domain name just fine. I'm stumped as to what could be the cause of this.
I tried restarting apache and mysql and both restarted without any issues. I'm guessing it's something on my hosts end, but if it's an issue on my end I'd rather not wait around for them to answer my ticket as I have work I need to get done. What could cause my server to all of a sudden only be accessible via SSH? I've tried to give as much information as possible, but please let me know if there's anything else you might need.
