Once again, one of the LNSs is being tad odd with RADIUS accounting, and giving people free internet access. Obviously this has to be fixed 
Seriously though, this is an annoying bug in the LNS code, which we have finally tracked down. We are doing routine LNS rolling upgrades during the week which will resolve this. It is in fact related to the fact one LNS stopped showing graphs for a day recently!
The control pages allow you to pick a preferred time of night for LNS upgrade to re-connect your line (a few seconds of outage) as we know some people work (and play) odd hours. Please talk to support if you need any help on this.
Sorry for any concern this has caused. LNS code is tested before release on test systems but this bug was rather obscure and did not always happen, and then took rather a long time to happen, hence not being picked up until we rolled it out on the live LNSs. The fact we run multiple LNSs and gradually introduce changes also means this issue is not affecting everyone, and problems can be quickly averted if they were more serious.
An LNS switch or PPP kill on your line does not cause a re-sync, and is normally only a few seconds. If you find issues with these, please do contact support as this can depend very much on your make of router.
Thank you for your understanding.
Note, there are some router upgrades as well this week but these should be seamless. |
