Interesting development: email from Access HeadEnd Manager – South Coast and South London via CEO/Faults office:

We have some resegmentation work scheduled for Wednesday 20th August to provide 4 additional downstream channels which will increase the amount of available bandwidth for the customer.

9am today, modem reboot and I have new wan ip because I am now on a new CMTS (sotn13)

Power levels and d/s SNR have changed slightly, possibly for the worse? Time will tell I guess:

New BQM graph:



with old graph:



New one seems to have a higher base latency Not sure why latency would be up when routing to the same headend ..
