There was a planned outage yesterday in area 31 and ever since then my cable connection has been basically unusable.
My download speeds are fine, although tests take a long time to start. My upload speeds are around (and often less than) 0.1 Mbps. The consequence is that a lot of stuff times out, and video (even voice) calls are out of the question. This behaviour can easily be explained by the graph below:
Just been on the phone to support, and they can't see a problem. We went through the usual nonsense of "maybe websites are slow to load because lots of people are using them", and switching to VM's own router instead of mine. Of course it made no difference. The support script seems to focus entirely on download speeds and completely ignores upload.
It's been escalated, and I have a ticket number. I'm posting this here to a) vent a bit and b) be able to point to this graph (and complaint) in the future.

I'm so annoyed and Virgin Media. I spoke to a second (and admittedly much better) support agent yesterday evening and I at least have an engineer booked. However, I have to wait until next Thursday and I very much doubt they'll be able to do anything to resolve this. Hopefully they can at least confirm that it is definitely an upstream problem.
I also genuinely don't understand how VM's own diagnostics can't detect a problem like this, when third party tools like the thinkbroadband.com monitor clearly show my connection is a mess. What are they even testing for?!

Hey @rsherhod, thanks for the reply on the forums.
I'm sorry to see the issues with the connection.
I do apologise that no one had noticed this, I've had a look on the system and a reading couldn't even be made.
Looking at the graphs - this definitely does require an engineer appointment.
Let's see how it goes Thursday with the appointment.
Kind regards,
Ilyas.

Thank you for looking into this and acknowledging that there's definitely a problem.
Do you know if I'll be able to claim some form of compensation for this lost connection. I have had to use my mobile phone as a wifi hotspot and I've already burned through a data top up, just doing video calls for work.

Hello rsherhod,
Just a quick message to see how todays visit went?
What did the Technician advise?
How are things looking now?
