We've had two occasions where a reasonable number of lines have dropped their PPP connected and logged back in. This has happened at 11:44 and 12:01.
Most of the lines have been TalkTalk, but not all. We're investigating further
Over the past couple of months we have seen a very small number of TalkTalk lines not log back in to us after maintenance or outages within the TalkTalk network. In these cases we need to involve TalkTalk staff to manually clear the stuck session.The cause of this problem has been down to some of TalkTalk's routers being unable to cope with the high number of reconnects after an outage has been fixed or planned work has been completed.
To solve this problem, TalkTalk are upgrading the software in these routers. They expect to have updated all their routers within a couple of weeks.
