I have Moodle site (3.4) located on a external hosting Virtual Cloud server (FastComet, 6 core, 8 GB RAM, 160 GB harddisk). I have recently noticed that my site has been coming much slower when accessed from the computers at my university and I am getting many more "server unavailable" messages. At home, from cell phone, or using a VPN to mask IP, the speeds are very good and what I expect.
I am pretty much a novice at server administration or maintenance, but is there some setting in the Moodle site administration or in my cPanel that would solve this problem.
