Peak time latency spikes
Quote from: mike0381 Thanks Chris, I appreciate your help.
That's been fixed for you, try a speedtest agian and let me know the outcome.
Edit - Typo in url
So I get the impression that the reconfiguration of the line cards on the PCL gateway routers has made a significant improvement.
@Digital care team
Any definitive conclusions yet from the data gathered last night?
As an aside, I've been on a PTN gateway (ptn-ag04) for the past week or so and seen no slow downs. I understand it hasn't been "reconfigured" yet, but I still saw an improvement in my TBB graph last night.
Thursday night. Nobody home/no internet usage:
Compared with Tuesday night. Also nobody home/no internet usage:
So I seem to have benefitted from the changes, even though my gateway hasn't been updated.

[quote=Chris]Dropping from 6.9Mb to 6.7Mb really isn't a huge drop and isn't a significant change. I'm sorry to say but that's well within the acceptable range of speeds for a broadband service.
I'm not particularly worried about it until it drops below about 6.0Mbps
I just wanted to point out for the record, that until 09:30 on 7th March, my latency had been in the order of 18 or 19ms and my speed tests were nearly always in the range 6.95 to 7.15Mbps.
Something at that moment, as captured on my TBB graph for that day did NOT appear in my routers connection log, and from that moment on my results have been consistently 10ms slower and at least 485Kbps lower than before. Whatever that change was, is NOT as a consequence of my IP profile changing, and my ADSL modem connection is extremely stable and has exactly the same margins, attenuation, sync speed, etc, as it has always had.
So I am merely pointing out that something that was not down to my local connection (and therefore must presumably be in either the PN or BT network) has changed. Whatever that change was ALSO altered the symptoms that my connection experiences in the evenings, before I always had excellent speed test results but the latency went to ridiculous levels, but ever since the latency goes up a bit but the speed test results are either 500Kbps slower than before or they have collapsed to an unusable level.
So I am just trying to highlight that I can identify a very specific moment in time which you might be able to correlate to events that you know about on the network, because whatever that difference is has made my connection behave differently under these peak time difficulties.
Therefore I am not complaining, just wanting to help.
Just for the record my result this morning is -
20CN on 'pcl-ag01'
I just realized from this result that it is a bit odd that the difference in speed results is EXACTLY 500Kbps !
That seems a nice round number ? - is it a clue ?, what change would lose 10ms and 500Kbps ?
@Anotherone - I get identical results from http://www.mybroadbandspeed.co.uk/ and http://www.speedtest.net/.
When I have been posting results in this thread I have generally run a speedtest on BOTH of those tools (to check for consistency), but I tend to post here the results from http://www.speedtest.net/ as that shows the PING value as well as the speed.
I have been using http://www.mybroadbandspeed.co.uk/ to take results every 5 minutes - because that tool has a convenient graph which is helpful in plotting the trend of how speeds throughout the evening are progressing.

Your last comments are very true, exactly what I've found, and because I hadn't used it for a while, I hadn't made use of the graphing. Perhaps it's working so well because it's now under-used 
Thanks for the update, Kelly. Fingers crossed! I guess you'll all be looking forward to getting back to Thursday nights out 
Right I'm down 16Mbps+ already....Ping is ok and upload is normal.. Im on pcl-ag03
Just jumped to ptn-ag03 and its even worse...
Not too shabby on ptn-ag02...
Going to be in and out until about 8, and I'll test again then.

Ok, Think I'll settle for this one for a little while... pcl-ag03....Almost back to my normal..ALMOST..
Nope, that ones gone down the pan now as well..I've had enough of this now its getting beyond a joke!!!
