Sometime next week, we'll be taking down the Foxcloud Synchronization Server for a while to upgrade it to the upcoming release of Cosmo 0.3. The upgrade wil give us some additional headroom in terms of total number of end-user accounts, as well as allow for the possibility of non-English characters in usernames, first name, and last name fields.
During the downtime, users won't be able to sync, create new accounts, or view their bookmarks on My.Foxcloud. We'll try to keep downtime to a minimum, but the upgrade will be a bit more complex than ones we done in the past as it involves migrating everyone's data from the current version of Cosmo to the new one. We'll post here when we start and when we complete the transition.
