Since mid-December 2019 I have had completely unusable latency to all servers globally, averaging around ~120 to those in Europe. This is across all applications including VOIP clients, games and video streaming services. My download and upload speeds are lower than what is expected from my package but they are acceptable, all I want to be fixed is this latency.

 as you can see in my BQM, latency recovers to "normal" values in the middle of the night and returns to garbage soon after. This has been happening for around 4 months, well before COVID-19, so whilst I understand a fix will take much longer to roll out during these times, I don't think that is the cause for why my latency is this high, as these issues predate the pandemic.

That BQM looks like an over utilised area.  The PostRS errors are indicative of noise on the circuit. Reboot your Hub and keep an eye on the PostRS figures, if they increase quickly then an engineer will need to fix.  As for over utilisation VM would have to comment .....

[JA_Foster]

Hi, thanks for the response. We've had an engineer over to clear the noise once before and iirc that fixed it for a while, but it seems to go back to being quite bad again relatively quickly. Could you explain what you mean by over utilised area?

[JA_Foster]

To update, latency is bad today but better than yesterday, assumedly because fewer people are working from home on a Saturday so there is less traffic. I am in the SM5 area and have had a few people in the same and neighbouring postcodes reporting the same issue, any idea on the cause of this or an ETA for a fix?

[lol58]

We have also been having latency issues for months. Normally just a day or 2 midweek in the evenings however this past week it has been unbearable. Normal browsing works reasonably well however any form of online gaming is a no go and video conferance calls (now we're all working from home) are hit and miss at best. When using discord the "Voice Connected" indicator is up and down like a yoyo. Currently running BQM, does not look great.

[JA_Foster]

Just hoping they will give us an ETA on a fix, so far they haven't said anything to me.

[lol58]

hopefully yes. However i havent managed to get through to anyone on the phone to be able to report it, they just point me towards the website then hangup. had the BQM running since yesterday,
