I've also noticed that there have been speed issues over the last few days on our site, and even a few times the pages have failed to load and needed an F5. This is certainly new to me, because the site is usually very nippy. This has been happening when visiting from work and home, so I know it's not a local internet issue as other web browsing has been fine.
not sure if anyone else is having this issue but i seem to have lost the template from my site its all white!!!! and running very very slow this is at 1822 gmt
