For two days last week, I had trouble accessing the chat. The site either wouldn't load, or wouldn't load fully, or render awfully (see below), or I couldn't post messages... I only had trouble when doing so from work while it was fine from home, it was worse in the mornings (GMT+1) and better in the evenings, FF was worse than IE, all of stackoverflow.com was fine, only the chat acted up.
Since it's only been bad from work, I put it down to some quirk in my company's Internet connection. However, as I found out later, others had this problem, too, and it was only Germans reporting it.
The trouble is, it's back today.
Anyone else having trouble accessing the chat?
