Once again the server was hit. At around 8pm yesterday evening the services were unreachable for about 30 minutes, the transports for about 60 minutes.

For sure there will be another incident, but this time everything will get logged. From what we then read out of the logs we will choose how we react. If it has something to do with Nimbuzz, we will block Nimbuzz completely.

Again we suffered a DoS attack. The Jabber services and website were down from ~10:45pm to 00:30am.

For sure we have to do something about this. We are already digging into this, also recieving feedback from other Jabber server admins. Maybe abusive Nimbuzz accounts are the reason and, if this turns out to be true, we are also thinking about firewalling Nimbuzz.

What would you think about blocking Nimbuzz? Are you having friends from Nimbuzz in your roster? Tell us your opinion.
