Problem with Jabber database

Unfortunally there was a major problem with the database for all accounts of the domain (not accounts from other domains, like

Finally we decided to restore a backup from 4th/5th of May 2010 (day of the server move) and had to take the Jabber server down for about 2 hours.

Affected are just the contact lists and contact groups. This means that as an affected user of this you have to add/delete all buddies you changed since then.

We really apologize for the trouble caused, especially because the backup is one week old.

The question remains why we just got 20 rows of data inside our current database backup from this morning, missing 150000 (!) other rows. We will take a deep look into the backup process.

Proper certificates for secondary domains

To avoid login errors or messages and also to avoid certain problems with server-to-server connections we installed proper certificates for the secondary domains today.

We had to restart the Jabber services several times, sorry. The ejabberd config file isn’t commented very good, also Google didn’t tell us the correct settings in the first place. But everything works fine now.

PS: For old SSL connections to port 5223 there are no dynamic certificates. This just isn’t possible because of how SSL works.

Network problems for hours

Our provider experienced network problems starting yesterday (05/06/2010) at 2pm CEST. The outages covered a lot of ISPs. T-Online and Alice worked here in Germany, a lot of others like KabelBW and Strato did not work. These severe problems went away at about 6pm, but we still experienced some problems until this morning. According to our server provider the problems are gone now. The problems were cause by a external attack with more than 50 gbits.
