Seems to be running fine for me over the last few days.
I've certainly experienced all sorts of speed issues relating to AV software and firewalls / content filtering etc.
I've also experienced some issues with specific sites that are *very* slow to load for a few days and then go back to normal for no reason at all - best guess is that it seems to have been something related to BT.
It's generally taken the form of the browser not loading the CSS file, indicated by the counter at the bottom of the browser stalling, eg 38 of 61 items loaded.
It generally affects a few sites, not just AN, but all with the same symptom.
The only way I can make the site run slowly is when I'm uploading pics, but chucking 20Mb+ through a slow upload connection is
guaranteed to mess things up!
