I noticed the same thing yesterday, but thought it was probably just routine maintenance. When I saw that Diigo was still down this afternoon, that got me worrying. I've also been worried that this may be a sign of them going under. Diigo is still down for me, however. I haven't seen it up even once since yesterday afternoon. Are you still able to access it?
