I'm on a VDSL line 50 mbit from German Telekom, and every night my router has to re-establish the connection to get a new public IP. According to the log files from my router this whole process takes only a couple of seconds, but in the Monthly probe report from atlas the time between Disconnected and new Connected is around 20 to 30 minutes, see examples below: > > +---------------------+---------------------+------------+--------------+ > | Connected (UTC) | Disconnected (UTC) | Connected | Disconnected | > |---------------------+---------------------+------------+--------------+ > | 2015-12-26 02:35:51 | 2015-12-27 02:06:06 | 0d 23:30 | 0d 00:27 | > | 2015-12-27 02:31:20 | 2015-12-28 02:04:36 | 0d 23:33 | 0d 00:25 | > | 2015-12-28 02:39:09 | 2015-12-29 02:04:29 | 0d 23:25 | 0d 00:34 | > | 2015-12-29 02:31:40 | 2015-12-30 02:03:09 | 0d 23:31 | 0d 00:27 | > > And this reports my router (times in CET) > > 27.12.15 03:07:12 Die Internetverbindung wird kurz unterbrochen, um der Zwangstrennung durch den Anbieter zuvorzukommen. > 27.12.15 03:07:15 Internetverbindung wurde getrennt. > 27.12.15 03:07:16 Internetverbindung wurde erfolgreich hergestellt.
