We've posted a service status.
Let us know if you notice any difference where you would normally receive the 'concentrator not reachable' message.

Jan 01 00:00:47 daemon pppd[551]: PPP: PPP Server No Response !!!
Jan 01 00:00:47 daemon pppd[551]: Doing disconnect
Jan 01 00:00:50 daemon pppd[551]: PPP: Start to connect ...
Jan 01 00:01:13 daemon pppd[551]: Couldn't get channel number: Transport endpoint is not connected
Is the loop i get following being kicked
I just hope the changes will be reversed straight away should their be any problems such as what Bob Pullen says Here
Quote he 'ppp keepalive' setting is based on the edge router/gateway getting an ECHO reply from the customer's equipment. There's a risk that lowering the timer could cause unwanted disconnections every 90-120s if something doesn't go as planned.

If I physically power off (not reboot) the modem I see this issue, and it still happens.
I have plenty of other kit i can try next time I'm home.

If people find that things aren't working then we're going to need to capture what's happening across the network when the problem occurs. Best way to do this would be:
PPPoE router <— hub —> BT vDSL modem
Then plug a laptop or similar into the hub and capture the traffic using Wireshark /before/ the router is powercycled and keep capturing until the PPPoE connection is re-established.

Killed it at 9.40.18.
Couldn't establish a PPP connection until 9.46.51.
I was connected to ptn-ag03 before taking the connection down (in case anyone wants to look at the logs on that server).
So doesn't look to be any better. Back in goes the hack...!

Did you get the concentrator not reachable? I've checked your log and it shows you disconnected at 12:08pm and reconnected at 12:09pm.

Power cycled just the router Draytek 2130n log was showing "pppd[10309]: Timeout waiting for PADO packets" until about 7:40 after reboot.
Will try again later with syslog enabled to see if a can get something more meaningful.

Just power cycled and unit comes up and reconnects in just over 3 minutes, 40 seconds of that was the hardware coming up...
