OK.. here is an update on site performance:
Our content delivery network (CDN) seems to be having problems delivering content.
For example. this is a link to some of our JS code on the CDN:
http://linux.unix.netdna-cdn.com/cli...etin_global.js
I have had trouble getting the CDN code above to work.
But when I go directly to that code bypassing the CDN, it works fine.
https://www.unix.com/clientscript/vbulletin_global.js
So, I have disabled most (I'm sure not all... ) of the CDN code, updated the templates and flushed the memcache...
So, as the cache rebuilds, lets see if we see any improvement in site performance.
Thanks!
