Hey,

Thanks guys, this is really useful stuff.

We're aware of the fonts.com CDN 403'ing on us, but for now we're more
concerned about the fact we've had people reporting that the site/pages
take 2minutes plus to load or in extreme cases never loads!

The specific issue we've been trying to investigate seems to be that the
browser takes forever or never loads some of the images/css files, its hard
to reproduce as it's pretty inconsistent. But seems to affect 1-3 files and
is a different set of files each time. Opening those files in a new-tab
seems to have the same effect.

We were toying with the idea that it was a DNS thing but nearly everyone we
know seems to be reporting the site loads in under 3 seconds. I think this
perhaps suggests there's an underlying networking issue with their ISP.
 However other sites seem to load reasonably fine for the firm we've built
the site for, so it's got us a bit confused.

To clarify: when I say images/css not loading I mean there's a spinning
wheel next to those files in Firebug. I've done a 'netstat -an' on the
server and can see the browser has made a connection, although I've noticed
a few "TIME_WAIT" statuses, not sure what this indicates though or if
they're related to the files!

Anyone else experienced this kind of behaviour before from a Server or ISP?

Many Thanks
Adam.
