My latency in the last 24 hours has been steadily rising. One of the services I regularly connect to is reporting a constant 450ms instead of the usual 50-125ms (at peek).

Pings to Jolt which are normally around 50ms are also very high:

Nothing has changed at my end and there are no announcements on the IDNet main site. I've rebooted the modem/router but the high pings remain.

Connection Speed 7968 kbps 448 kbps
Line Attenuation 26.0 db 12.5 db
Noise Margin 6.3 db 22.0 db


This speed test result doesn't look too bad:

Speed Down 5177.67 Kbps ( 5.1 Mbps )
Speed Up 369.72 Kbps ( 0.4 Mbps )


Is anyone else having problems?

It seems that a couple of users have been experiencing this. It's good that you seemed to have narrowed it down, so definitely let IDNet know and hopefully they can look into it and get it sorted. :)

Further problems as you can see from my modem log (assuming I'm interpreting things correctly) I'm losing sync. I'm also having massive timeouts (lag spikes).

However the latency issues have gone at this moment in time ???

The sync drops are 99% certain to be local. Looking at the timing, I'd say BT were working on your exchange.

Pings seem back to the recent interleaved baseline for my telehouse-gw2-lo1.idnet.net connection, but not to the 20s that I used to enjoy. Need to run PingGraph at length to see if I still get episodes over 100+.  :o

BT speedtest is on the upper bumpstop. Yesterday's spread of degradation could hardly be exchange contention.

I haven't Rik, I wanted to do some more testing today and I thought I'd wait until Monday as I'm a little uncertain of what level of support is available over the weekend. Would you suggest I call them today?

I wouldn't suggest calling, but an email - it will get picked up Monday morning as it wouldn't be considered an emergency. It would be worth pointing to this thread.

Just a quick note to say IDNet support were unable to identify any problems and that things do indeed seem to be back to normal after the weekend.
