On Monday 24th November, at 3:15AM we will be upgrading the software on one of our L2TP servers (l2tp.aa.net.uk) 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.)
The upgrade completed successfully.
