Hey, thanks for getting back to me. I've checked and yes, the power levels are still roughly the same (+/- 0.1-0.3dBmV) both for the upstream and downstream.
I've noticed whenever the connection drops, when it re-establishes connection the pre- and post-RS errors are wiped and in some cases the channels are on a different frequency, perhaps because it has to renegotiate the connection, but the power levels of each channel are roughly within the same parameters. FWIW the error counts are generally quite small and usually only pre-RS.
There are no area-level faults recorded against my account on the online service status checker, nor on the automated service status number (whether I check for known faults or run a check myself directly).
I've used the online checker a few times before, it will record that there is a fault while my connection drops and potentially prompt us to book an engineer appointment, but while it's running it claims there are no issues. I believe there was an area-level outage in the past that was recorded there once that lasted for a few hours, but for the most part it comes back in the green.
Reckon I'm better off trying to book an appointment or should I wait until I'm outside the fault window to reduce the risk of cancellation or miscommunication?
