Over the last week or so I've found it often takes much longer that usual to move around this site; when I click on an internal link, eg to look at a post, nothing happens for what seems quite a large number of seconds. I don't think the problem can be at my end, because it only happens to me on SE23.com. Anyone got any wisdom?

Also, at the moment I'm not getting emails to alert me when there's a new post on a thread I've contributed to. This has happened before, but on that occasion it somehow got put right after a week or so.
