Huge Ping Delays: 1 to 2 seconds!


[link to this post]
 
Having some horrendous performance issues with my BT Broadband the last week or two. The fault was intermittent, and seemed to coincide with peak usage times, but now seems more frequent.

Connection to the exchange seems rock solid at around 6Meg. Normal ping is 50mSec and normal download speeds are solid 5Meg.

Everything feels really slow and sluggish, not surprisingly.

Is this likely to be a fault on my line, an exchange fault or congestion?

I have reported it as a fault after getting seriously frustrated earlier tonight, and it now shows up in the fault progress reports as having a red square around BT retail Servers.

Some data below, shows what I am seeing, but I am slightly concerned how this will pan out.., Anyone else had anything similar and was it resolved promptly, or have any ideas what is going on here?

Would also be good if there was some mechanism for attaching stuff like the below to the BT fault report!

yes, had a look but no mention of my area. I'm in Scotland.

Looks like it is getting a little better as night goes on, ( and traffic gets less?) but still not back to normal:

This is not normal.

Reboot your router, and try again. Fix the local issue first then re-test.

Its a Home Hub 2. If you tracroute or ping to it directly it appears to respond OK:
traceroute to bthomehub.home (192.168.1.254), 64 hops max, 72 byte packets
1 bthomehub (192.168.1.254) 1.080 ms 0.518 ms 0.456 ms

If you are going further it gives time values similar to those you have highlighted, which are still less 100msec when the overall delay is in the 1 to 2 seconds overall. Is this typical of an hh2, or is its response looking odd? I don't have another hub available to substitute for testing:

I don't know about the Home Hub itself, but hop 1 to a router is normally 1ms and at most 3ms, unless perhaps it is simultaneously streaming a download at high speed.

In reply to a post by IanBB:
All my O2 routers have displayed this apparent anamoly.

Good grief, well all I can say is, that must be a right piece of [censored] router to do that. Who the hell thinks a response time of 73ms is acceptable in the design of a piece of network equipment? I'd never let [censored] out to customers that did things like that.
