Sudden increase in ping

Ray · May 14, 2011, 08:51:56

I had a loss of ppp for some reason at 07:15 this morning and on reconnection my ping has suddenly gone up from a steady 13ms to 43ms, interleaving is still off.

Has anyone else seen anything like it this morning?

All ok here Ray, no issues with ping.

Umm......... that shows that you resynched and your throughput is lower, therefore you have more overhead and the SNR is higher.

Ray · May 14, 2011, 09:24:18

No, it didn't resynch, only lost ppp according to the router system uptime, and my SNR and throughput are still the same as they've always been, Dorset.

Pings are fine here, Ray. Are BT pulling anything apart in your area?

Ray · May 14, 2011, 11:50:55

Not that I'm aware of, Rik, though I did have a 2 hour outage at 2:00am about 3 days ago when one of Birmingham nodes that my exchange is on went down, though everything came back as normal afterwards.

Rik · May 14, 2011, 11:58:41

I really don't know what to suggest, Ray, beyond letting support know on Monday if the problem continues.

Ray · May 14, 2011, 12:02:23

I'll do that, Rik, seems strange that it's been running at 12-13 ever since I had interleaving turned off now it's jumped to 30-40, a reboot of the router has made no difference.

Rik · May 14, 2011, 12:07:27

Does the router indicate if interleaving is back on?

Ray · May 14, 2011, 12:14:45

It's still indicating that interleaving is off, Rik, and this BT speedtest seems to confirm that: -

Download speedachieved during the test was - 6364 Kbps
For your connection, the acceptable range of speeds is 1200-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 832 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps

Rik · May 14, 2011, 12:19:08

The speed seems to rule out congestion, so I don't know how to explain it, Ray.

Ray · May 14, 2011, 12:24:05

It's puzzling, Rik, something somewhere was certainly upgraded at the beginning of this week, last weekend I was struggling to get above 2Mbs speeds yet this week I've not had a test below 6Mbs.

Rik · May 14, 2011, 12:24:58

I wonder if BT have configured something wrongly?

Ray · May 14, 2011, 12:28:15

Yes, I was wondering that too, Rik.

Rik · May 14, 2011, 12:33:27

One day, all this will change.

Ray · May 14, 2011, 12:36:43

Will we still be around when it does, though, Rik.

Rik · May 14, 2011, 12:38:21

Probably not, but Lance may be.

Ray · May 14, 2011, 12:39:11

Probably the only one of us.

pctech · May 14, 2011, 15:03:57

Might be worth checking http://status.zen.co.uk/broadband/, had a loss of PPP during a late night surfing session and it turned out to be BT maintenance.

Ray · May 14, 2011, 15:30:48

Thanks, Mitch, nothing showing for this morning, but I see the outage I saw on the 12th was to change all the ATM line cards.

Steve · May 14, 2011, 18:59:28

What evidence are you using Ray to say that interleave has not been applied?

Rik · May 14, 2011, 19:00:17

Said the defence barrister.

Steve · May 14, 2011, 19:01:45

It was a bit stern

Not me but I had the same thing happen on my FTTC connection some while ago. I had a 7ms ping for about a month but a loss of ppp resulted in my ping jumping to 16ms. I believe I also lost around 5 Mb/s off my profile at the same time.
