Very strange BQM today

Massive spikes in latency since about 08:30 this morning. Anyone else seeing similar?

Not quite as bad, but similar:

My Broadband Ping

Not seeing this (CityFibre):

The IDNet response to my e-mail asking what was going on:

"I have looked at the service for that period and can see the line was being heavily saturated which would cause the latency you experienced.
"This may be caused by you being connected to a gateway in Manchester. I would advise rebooting your router so you connect to a more local one."

Two short disconnects at about 02:00 and 04:30 this morning and the graph is looking a lot more sensible but I have no idea whether that was Zen or IDNet.

All in all, less than helpful with no indication the IDNet are willing to take ownership of the problem or review their backhaul agreement with Zen.

I was with IDNet a few years ago and experienced the same issues due to Zens backhaul. Often rooted up to Manchester. At that time and I'm guessing its the same now, IDNet only have connectivity in London, so going up to Manchester just means all traffic then diverts back down to connect to IDNets gateway in London. Latency was over double, and there was more congestion. So I had to drop the connection several times to finally get on a direct route and it was a much better service. The snag was every couple of weeks the connection would drop overnight and come back up via Manchester, presumably a deliberate rebalancing by Zen of their network as I suspect a lot of people kept playing the same trick.

I hadn't had to play these sorts of hunt the best gateway games since PlusNet and ADSL years before. I complained, pointing out they boast the lowest latency service, but that wasn't the case if they kept routing me via Manchester, where in my case it was actually the worst latency I'd ever had. They said they knew it happened but nothing they can do, and weren't concerned in the slightest, so I left them.

Mostly the same here- the difference being that I don't do anything that's latency-sensitive so no real reason for me to complain or incentive to change ISP. But it's hardly a point in their favour.

Had an odd one last night: My Broadband Ping

Connection dropped briefly at 3am, came back up with a latency of ~20mSec rather than the usual ~8mSec. Nothing unusual there; usually it will stay that way for a few days to weeks when a repetition will put it back where it belongs. But only a ~15 minute delay this time, with a longer drop (a few minutes maybe). Manual intervention? Doesn't sound likely, but not impossible


eta- FTTC btw, Didcot exchange in south Oxfordshire

Have seen the same thing since Tuesday:
IDNet 25/02/2025

The interesting thing is that this line is a backup failover for my FTTH connection, so there is basically zero traffic travelling over it (300MB so far this month, so certainly not caused by intensive usage.

All fine here up north!

How does North Northumberland relate to "up north"?
