Just tried to log in to ECCIE (habit) and it popped up with me logged in:

Welcome to ECCIE!!!! The forums will be closed temporarily. Check in with us daily, as we will be back very soon.Thanks!

It had my username, but the link to my profile and private messages redirected back to the main page, so I have no idea if old posts will be retained. A traceroute shows the IP goes to the Netherlands, so maybe that's how they are planning to re-open.

I hope that this site continues, though. It was kind of nice and intimate.
