Hi List,

Since the recent denial of service attacks, I understand that some
measures were taken on the server side to prevent the attacks. In
particular, this notice:

2012-08-21: Another Denial of Service
The previous DDoS attack has started again. As before,
fallback measures are in place, but if your IM client doesn't
handle DNS SRV records correctly then you might not be able to
connect.

My client is Pidgin 2.10.5, and around this time of attacks I have
lost the ability to connect to jabber.org. (By the way, I am not a
gamer).

Below is the debug log. Can anyone see what the problem might be?
Would it be that Pidgin doesn't handle DNS SRV records correctly?

Many thanks,

Rob
