High latency in evenings since 24 March 2021

We have had latency problems every evening since 24 March 2021 (between 7 and 10 approximately). 

Trace route output:

Tracing route to forcesafesearch.google.com [216.239.38.120]
over a maximum of 30 hops:

1 * 2 ms 2 ms ttrouter [192.168.1.1]
2 208 ms 201 ms 204 ms ae51-ner001.irl.as13285.net [78.144.1.5]
3 102 ms 200 ms 204 ms ae51-scr101.thw.as13285.net [78.144.1.4]
4 205 ms 204 ms 204 ms 72.14.209.10
5 101 ms 92 ms 92 ms 209.85.248.229
6 140 ms 203 ms 203 ms 108.170.232.103
7 198 ms 203 ms 203 ms any-in-2678.1e100.net [216.239.38.120]

Trace complete.

However, a ping to 78.144.1.5 (second hop) returns:

Pinging 78.144.1.5 with 32 bytes of data:
Reply from 78.144.1.5: bytes=32 time=8ms TTL=62
Reply from 78.144.1.5: bytes=32 time=7ms TTL=62
Reply from 78.144.1.5: bytes=32 time=9ms TTL=62
Reply from 78.144.1.5: bytes=32 time=10ms TTL=62

Ping statistics for 78.144.1.5:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 7ms, Maximum = 10ms, Average = 8ms

But a ping from 78.144.1.4 (third hop) gives:

Pinging 78.144.1.4 with 32 bytes of data:
Reply from 78.144.1.4: bytes=32 time=166ms TTL=61
Reply from 78.144.1.4: bytes=32 time=178ms TTL=61
Reply from 78.144.1.4: bytes=32 time=195ms TTL=61
Reply from 78.144.1.4: bytes=32 time=214ms TTL=61

Ping statistics for 78.144.1.4:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 166ms, Maximum = 214ms, Average = 188ms

The latency appears to be between the second and third hop. Is this a problem at talktalk? During other times in the day we get a round trip latency of about 15 to 20ms which is normal for our connection. Before 24 March we did not have any noticeable deterioration in response during the evening, so this is something we haven't suffered with before.   

 

Can anyone offer any advice?

 

Thanks

Hi Chris,

 

Ok thanks for the update. Please let us know if this does happen again this evening and if possible if you can run a wired test and I can escalate this straight over for further investigation for you.

 

Thanks

Hi Michelle 

 

Yes I can run wired traces. The delay is clear between second and third hops at talktalk. Interestingly yesterday evening was the first evening where we didn’t suffer any increase in ping or any reduction in speed. Hopefully something has been fixed within your infrastructure but let’s see.

Hi BradTheLAD,

 

I'm sorry to hear this. Please can you create your own topic and we can look into this further for you.

 

Thanks

Hi Chris,

 

Ok thank you for confirming. Would it be possible to run a wired ping and trace route when the connection is ok and also again when the latency occurs and post the results into the thread. Can you also run a few wired speed test results using the TalkTalk Speed Tester and we can then pass this straight over to our Network Team for further investigation.

 

Thanks

Hi 

 

Yes, for the purposes of capturing the text files, I ran wirelessly from my laptop. My son games from a wired connection though and it’s the same. Stats are fine all day. It goes wrong about 7 in the evening and improves after 10/11 at night. This has been constant since 24 March. Never a problem before that date. Speed does drop in the evening as well but it’s latency that’s the main problem. The delay appears to be second to third hop. At bad times I can still ping 78.144.1.5 in 10 to 20 ms but 78.144.1.4 is over 100ms. Weirdly trace rt gives a much higher time for 78.144.1.5 to respond than a simple ping which suggests some kind of delay processing at that hop and forwarding the packet.

Hi, I have been experiencing the exact same issues. On the phone and the livechat to the helpline however it was like pulling teeth as 2 and a half hours into the conversation they had still not addressed my issue however ran 4 line tests saying it was all fine.

After the call, we tried resolving this by trying both wired and wireless connections, buying a second router, testing game servers, running speed tests etc. Speed tests came back at a stable 25ping however as soon as jumping into a game (tried multiple from a range of developers), it was bouncing between 250 and 1020 making everything unplayable.

We have had the issue constantly cropping up in the evenings however download speeds have not suffered, only latency.

Any advice?

Hi Chris,

 

I'm sorry for the delay. I've run a test on the line now which hasn't detected a fault and the connection stats look ok. Do the speeds also drop at the same time? The results are showing slightly high pings to the router. Just to confirm, did you run this test wireless?

 

Thanks

Hi @ChrisAPL,

 

For one of the TalkTalk staff on this community to be able to look into this you will need to update your community profile to include your name, landline telephone number that your TalkTalk service is provided on & an alternative contact number. This will allow them to identify you, and they will then be able to help.

 

Don't post any personal details in this thread, just add them to your community profile.

 

The staff here won't be around now until Tuesday, but they should be able to respond to this post early next week to help.
