On Wednesday 4th February, at 3:15AM we will be upgrading the software on the other L2TP server (l2tp.aa.net.uk). We upgraded the first one last week. This will cause some L2TP customers to drop and reconnect twice as this happens. (Twice, as whilst the router is upgraded connections will reconnect to the other L2TP server, and then will moved back once the upgrade has completed.)
This was completed.
