My Broadband Ping
Pings jumped from mid 20s to high 30s. Did a reboot. No change.

Interleaving gone on?
My broadband basic info/help site - www.robertos.me.uk
My domains,website and mail hosting - Tsohost. Internet connection - Plusnet Value Fibre.

Probably unrelated, but I had some problems first thing. Complete loss of connectivity.
Did the usual trick of power down the router, go to have my bath, and try again later. Got back on, no problems.
Couldn't see any acknowledgement of a problem in the Service Status, but note they did do some planned router maintenance between 02:00 and 07:00 this morning, so assume it was some legacy of that.

Nope. Still fastpath. Uptime of 1hr 47min. Errors shows:
Downstream :
FEC : 0
CRC : 14
HEC : 13
Upstream :
FEC : 0
CRC : 0
HEC : 0
So I would not think that interleave / fastpath is an issue in this case, although my activity in that period has not been particularly high.

Yes, the last three services status announcements predict work in the 'early morning', which ties in to the 3am blip. Looks a little like I've been switched to another gateway or network.

HI camieabz,
How are the pings now?

I've seen similar in the past and some time later it went back to normal. I think it's probably due to BT changing the tunnelled route between your exchange and the Plusnet gateways.

Saw your post and it was no different. Rebooted and now up to high 40s.

Do a traceroute - presumably you have changed gateway.

Do you have an old one to compare? This happens to me on Zen sometimes when I get put onto Leeds rather than rochdale
Unless something has changed/broken in the BT side of network so they are routing you via an alternative and longer path.

So...all different hops.
Also:
You are currently connected to the gateway known as pcl-ag04.
This is located in City Lifeline House.

The latency is high from the very first hop, so would rule out plusnet routing beyond there. It would either be something in the BT network, or the first hop, at plusnet, which is why it's so high.
Someone else will know but I'm sure all their equipment is together (or rather all in London), so it shouldn't really make that much difference what gateway you get on, maybe a few ms if they have a few different sites in London, not tens of ms, therefore my thoughts would be a routing change in the BT network.
And I wouldn't have thought it would be a RAS change either becasuse there is only 1 in Scotland.
Some of this info is probably out of date and someone will come along and correct me!

Yup. Definitely a gateway issue.
I assume all the ADSL1 plebs are shoved together on the same (slow) gateway and are fighting for priority or summat.

That's not what I'm saying. It's most definitely NOT a gateway issue. Not only have I seen significantly different pings on the same gateway, I've seen it change without a disconnect. It can only be down to the BT routing between the exchange and the gateways.
Also 20CN "plebs" now use IPSC and I'm pretty sure also come in through the 10 gig connections.

Well it's still a problem, and the one thing that changed in that period was my gateway.

How can you say that? You have absolutely no visibility of the tunnelled route between your exchange and the Plusnet gateways. I am almost positive that if you kept reconnecting until you were back on the same gateway as before you'd find the latency was still elevated.

So what's causing it, and do you have visible proof of the cause?

How many times do I have to say the same thing before you stop coming back with dumb relies? It's the BT routing.
Whilst the last jump I've seen it is not as significant a jump as you've seen, I do have proof that this happens without a change of gateway. I have a simple scheduled command file that logs my current gateway every five minutes. Here's the log for between 11am and midday on 25th Feb:

As you can see the gateway is unchanged. In addition my router uptime shows I've had a continuous connection going back over 18 days: http://imageshack.us/photo/my-images/402/routeruptim...
Now if you look at the latency graph from the SamKnows monitoring you can see a step change occurred between 11am and midday: http://imageshack.us/photo/my-images/607/latency.png/
The ONLY thing that can have changed is on the BT network.

Check your attitude Jelv. Your snippyness doesn't fix my problem. My gateway changed between the changes in ping times, so the assumption is valid. Further more, in the past, almost all similar changes in ping have been down to gateway changes on a reboot.
Look at the graph:
http://www.camieabz.co.uk/ping.png
Note the red line at 3am and the subsequent rise in ping. Said red line is similar to a router reboot, but obviously I didn't reboot the router as I was sleeping.
As for "How can you say that?, all I said was that the only thing that had changed (from my perspective) was the gateway. One's perspective is all one has to go on, so be slightly less quick to jump on folk for it.
Now waiting for a PN rep who can solve the problem.

Cammie..have you tried mybroadband speed tests when this is happening? I have been getting wild fluctuations. I am currently on ptn-ag01
|
|
|
To be fair Camie - while the increase may be to do with the gateway you are connected to, does not mean the problem with the gateway, the BT routing may differ between what gateway you get landed on, or it may have just changed by coincidence.
It would be unusual for a gateway that is defective or overloaded to increase latency uniformly, that is not the manner they operate in. The increase in latency is down to the change in routing which has occured, which is very likely within the BT network.
You are not seeing the tens of hops you are going through in the BT network so even probability alone suggests it's not the first gateway.

mybroadbandspeed is getting hit with people who have recently gone on to the FTTC 80/20 trial. Even before that it was showing signs of being overloaded and PN have admitted it needs an upgrade. It's results should be ignored at present.
