Slow or incomplete page loading

Hi,
First of all, I just like to say Thank you to everyone at CG. I love this web site and I use it all the time. I greatly appreciate all the guidance I've received here over the years.

Lately, I've had some difficulty with viewing pages. I'll have to refresh a page at least 4-5 times before it displays properly.
Has anyone else had this problem? I have a T1 connection with a boat load of security (smartfilters, firewalls etc.) so I don't really know where the problem is.
It only seems to happen when I visit CG.

Thank you,
