We'll be taking Jaiku offline at 03:00 pm PST (22:00 GMT) on Wednesday, March 11th, to migrate jaiku.com to Google App Engine. We expect about 24 hours of downtime. We know how important it is for you that Jaiku stays up and running, so we'll be doing everything we can to make the downtime as short as possible. We'll post an update here when we're back.
Thanks for your patience!
