Recent increase in Ping

Sorry to moan guys but I have noticed a 10ms increase in ping to websites such as bbc.co.uk

use to be in mid teens but now mid 20's

the increase seems to be starting from 3rd hop

DLM has changed connection from Fast Path to Interleaved. Nowt you can do about it.

Not so sure....

The router to the gateway is 14ms which is quite normal for fastpath, unlikely to be interleaved, and then within their own network (ISP), it increases by 10~ms.

Matt

exactly

are you sure?

14ms to gateways is high, some isps can get the user to london for under 10ms over 100miles.

my gateway (on diff isp) is 5ms.

My base latency on fast path with IDNet was 13ms. On moving to PlusNet it stayed the same for a while then went up to 21ms when interleaving was turned on.

Yes. Such low latency depends on your locality too.

The key was in the OPs original post where he said latency has gone up 10ms and is now mid-20s, which if you review the trace, shows 14ms on the second hop (gateway) increasing by around 10ms on the third hop which then remains 25~ throughout.

This shows the increase is within the PN network, not the line, otherwise second hop would have the increase too.

Matt

Possibly restricted to that gateway?

Mine is fine (though this is from an ADSL2+line):

Mine is very similar to yours and I'm on the same gateway as the OP:

If that's your trace, you aren't on the same gateway. OP is on a ptw gateway, that trace shows PCL.

(I'm having a look at what's caused that change)
