I wonder whether it could perhaps be related to more mid-week football and having it on Prime - everyone has Prime - well almost
I saw an article on TBB homepage saying openreach saw peak traffic... Be interesting to see whether it dies down a little soon. If not, then what has changed?... HeyBB need to look into this.

CGNAT is definitely a thing with HBB now, sadly.

You can ask to be put on a dynamic public IP. They should oblige.

Interesting. I've had a lot of peak time evening problems *before* the line card install. Now its much better

Performance
Before Line Card install
After Line Card install

Latency over the past 24hrs averages 6ms to 8.8.8.8 during evening peak hours

Not perfect but massive improvement.

I had an engineer out this week and can confirm they'll take you off CGNAT if you ask.

The engineer was visiting because I talked to support about poor performance in the evening.
F&W visited and was unable to see anything wrong with the fibre dB levels.

They swapped out my ONT and transferred me from PPPoE to DHCP. ports stopped working, I let them know and they got support to get me off the CGNAT, which worked fine.

He suspected it was my router causing the poor performance (a NanoPi R4S running openwrt 23.05). Which is quite capable of doing 1gbps, so I had my doubts!

However, I've since connected a laptop directly to the ONT and confirmed the performance is exactly the same as through my network.
At the time the engineer wasn't able to connect his laptop directly, unfortunately.

I'm on the 900/900 Package and for the last few weeks the speed has been all over the place, and very cyclical with the time that it dips.

(ignore the 800mbps change for the last few days of download, I turned on SQM)

Latency & Packet loss seems to be a problem at peak hours too:

Wonderful to know about the CGNAT!

Your graph looks VERY similar to how mine was - same increase in minimum latency as well as average/max + higher packet loss.
Ours seem a lot worse than other HBB users who provided their graphs here.

If you don't mind me asking, roughly where are you based? - I'm in HP2.

Close, but not too close. I'm in mole valley, RH4.

It's only been this bad for a few weeks. I've submitted a few graphs to support and the evidence that the problem seems to be at their end. So we'll see if they do anything.

It's been awful tonight. Can't even watch YouTube in 1080p without constant buffering.

Ignore the total drop out from 5-6pm. There was an octopus energy saving session! The first two drop outs were overnight maintenence they were doing.

A few times now the DHCP renew request on the wan side has failed, so no IP address allocated, and no Internet.

I'm seeing the same - massive packet loss during "peak" periods.

It seems that "upgrading the network server" has broken something.

Must be localised to the network that serves your area. I don't see this where I am.

Latency to 8.8.8.8

I wonder what was changed.

Yeah, it followed their "maintenance".

I emailed them and it seem they're on it:

We understand that you've been experiencing a degradation of service.

Please be informed that there will be maintenance work today, Wednesday December 13th. We expect 2 bursts of 5 minute intervals and your service will be back online no later than 2pm today.
