--- bbc.co.uk ping statistics ---
1000 packets transmitted, 1000 received, 0% packet loss, time 1000550ms
rtt min/avg/max/mdev = 17.923/20.409/53.681/3.449 ms
Full ping log here if needed: http://pastebin.com/ZBYkmLkr
Normal ping for bbc.co.uk would be 17-18ms on my (currently interleaved) connection

These are from the line with fixed IP address ending .54
I also have a second line I have just dedicated to failover so should have minimal traffic.
I've added the live BQM to the website link on my profile.

At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.

Quote from: ejs At what point will all the extra ICMP ping packets start to impact the network performance? ICMP appears to be given titanium (0xa0) classification - obviously you wouldn't want all that web traffic (which gets a lower classification) spoiling people's ping graphs.
A long long time. This graph shows ICMP and NTP traffic (below the line is download, above the line is upload) so it's peaking at less than 15Mbps which is fraction of a percent of overall capacity.

Quote from: ejs .......... What unfortunate destination should we all ping to test this theory?
I usually ping 212.159.6.10 just to make sure it's working, but any one of the four would do
Slightly more seriously, as I don't have a TBB monitor running atm, I don't know if the attached helps, on pcl-ag07 20CN, the first is what I was seeing yesterday evening peak, normal pings in the past are more like the later part of the second graph. You can ignore the extreme peak at 2204-2206 & the strange one at 2238-2240 both due to local "activity".

Quote from: jelv I have no ping test history before February this year.
Is the same for me, graph image just won't load before Feb. 1st this year. TBB must have lost them or something.

But they seem to want less detail ie the rudimentary windows tracert and ping along with wire shark captures , as im behind a router does it mean that i would have to connect direct to the pc instead of via the router to show what traffic priority HTTP is being given during peak times, If the answer to that is yes then this would create a problem, as the gateway would change therefore the results i have taken wouldn't be current any longer ,
It seems to me there is far too many obstacles thrown in the way and hoops to be jumped through in order to get a known issue looked at , not impressed

I've just reviewed your ticket and asked Dave to have a look.
