slow speed and high ping

In the evenings since the 20th or so I've seen really slow speeds and high ping its at its worst tonight 107ms to a server thats normally 19, 15mb down now at 6 its also constantly changing, ping, speed, just seems random now but whats strange is btw speed test site says 15mb, 10mb  but anywhere else and trying to watch anything online is almost impossible with constant buffering. ran trace routes to bbc as follows
Tracing route to bbc.co.uk [212.58.244.22]
over a maximum of 30 hops:
  1    2 ms    2 ms    1 ms  dsldevice.lan [192.168.1.254]
  2  114 ms  110 ms  101 ms  lo0.11.central11.pcl-bng01.plus.net [195.166.130
.139]
  3  108 ms  105 ms  114 ms  irb.11.PCL-CR02.plus.net [84.93.249.98]
  4  110 ms  102 ms  102 ms  ae1.ptw-cr02.plus.net [195.166.129.2]
  5  118 ms  112 ms  106 ms  ae2.ptw-cr01.plus.net [195.166.129.4]
  6  114 ms  107 ms    96 ms  kingston-gw.thdo.bbc.co.uk [212.58.239.6]
  7    *        *        *    Request timed out.
  8    *        *        *    Request timed out.
  9  109 ms  124 ms  113 ms  ae0.er01.telhc.bbc.co.uk [132.185.254.109]
10  117 ms  115 ms  125 ms  132.185.255.148
11  117 ms  111 ms  108 ms  212.58.244.22
Trace complete.
Wired or wireless i get the same results. pc (wired) laptop (wired+wireless) phones
Router stats as follows
5 - Mode ADSL
6 - Uptime: 0 days 01:57:07 (i reset it but it had no effect, was 14 days prior)
7 - Data rate: 1267/17415
8 - Maximum data rate: 1268/17624
9 - Noise margin: 6.0/3.5
10 - Line attenuation: 16.6/29.0
Really impossible to play games with this latency as its 140-180 ping to eu servers

Re: slow speed and high ping

I recently ran through more thread posts and have come to the conclusion it was plsunet congestion at gateway pcl-bng01 disconnected for a minute and got pcl-bng02 and everything was fine

Re: slow speed and high ping

Well its back again which is always pleasent does anyone know if repeatedly disconnecting (ppp session only) and reconnecting will effect sync speed or ip profile?

Re: slow speed and high ping

Sorry i dont know the answer to your question - just to say that i have almost exactly the same problem.  Slower downloads and uploads and higher ping.  I will post a separate thread with my concerns (luckily for me i am over my 12 month contract)

Re: slow speed and high ping

Hi Folks Smiley
Hopefully we can get to the bottom of this - although, are you guys up north / in NI / Scotland? there's an interesting thread started over Here which looks like this could be down to BTW struggling with the current weather conditions.
Thoughts appreciated Smiley

Re: slow speed and high ping

Hi  Smiley
i've also noticed the network slowing down in the evenings over the last few days. My broadband is stable, with no line problems. What has been very noticeable is that responses to the Plusnet gateway have more than trebled. Normally 30-40ms is what i'd expect to see, now its regularly in the 120ms and has gone as high as over 400ms on occasion. It's as if traffic is being shunted around a less than optimal routing. I'm not seeing any packet loss so its clean but its just a very noticeable dip in what is usually great performance. I'ver tried switching gateways by disconnecting and reconnecting but the issue is the same on different BNG gateways:
Examples:
traceroute to portal.plus.net (212.159.8.2), 30 hops max, 40 byte packets
1  lo0.10.central10.ptn-bng01.plus.net (195.166.128.22Cool  119.096 ms  117.542 ms  116.515 ms
2  irb.10.PTW-CR01.plus.net (84.93.249.1)  114.853 ms  120.848 ms  119.449 ms
3  te9-4.ptn-gw01.plus.net (195.166.129.33)  123.469 ms

central10.ptn-bng01.plus.net (195.166.128.22Cool  119.096 ms  117.542 ms  116.515 ms

----------------------------------------------------------------------------------------------------------------------------
traceroute to portal.plus.net (212.159.9.2), 30 hops max, 40 byte packets
1  lo0.10.Central10.pcl-bng04.plus.net (195.166.130.177)  144.624 ms  121.346 ms  123.673 ms
2  irb.10.PCL-CR02.plus.net (84.93.249.82)  122.968 ms irb.10.PCL-CR01.plus.net (84.93.249.81)  122.793 ms irb.10.PCL-CR02.plus.net (84.93.249.82)  115.777 ms
3  ae2.pcl-cr01.plus.net (195.166.129.6)  115.851 ms  116.393 ms  147.971 ms

Central10.pcl-bng04.plus.net (195.166.130.177)  144.624 ms  121.346 ms  123.673 ms
I am up North but its a fairly central location without major weather problems...traffic must be going the long way around to get to the above gateways?

Re: slow speed and high ping

Thanks Matt_2k34, the similar thread in the fibre forum had an update from PN to advise a POP in Glasgow was causing issues last night and some hardware was replaced around 4am. My gateway ip has changed overnight and responses are now very good indeed:
traceroute to portal.plus.net (212.159.8.2), 30 hops max, 40 byte packets
1  lo0-central10.pcl-ag03.plus.net (195.166.128.184)  32.442 ms  26.195 ms  17.23 ms
2  link-a-central10.pcl-gw01.plus.net (212.159.2.16Cool  17.742 ms  17.072 ms  17.347 ms
3  xe-10-2-0.pcl-cr01.plus.net (212.159.0.200)  17.572 ms  17.415 ms  17.35 ms

central10.pcl-ag03.plus.net (195.166.128.184)  32.442 ms  26.195 ms  17.23 ms
All good Smiley
