Strange DNS failures

[mitchgixer6]

Hi all

I have been having issues with my connection recently, mainly slower speeds (still hitting 30mbs) and disconnects. 

I have just spent 40 minutes on chat with the tech team trying to nail it down, but no errors with the line showing, suggested it may be wiring in my house but nothing here has recently changed. 

I was just looking at my router setting and noticed some strange behaviur in the logs. Lots of DNS name resolution failures during the night when there would be no acces on my connection.

Anyone have a clue whats going on or if this could be the cause of my instability?

Thanks

Hi mitchgixer6

The line test is detecting a potential issue so I have passed this over to Openreach to be investigated by a line engineer.

The engineer will investigate this fault externally and I will monitor for additional updates.

Thanks

Hi mitchgixer6

I will run some more tests now and post back shortly.

Thanks

Hi Debbie 

I'm not sure there is much point tbh. The router I have now is only a week old and is still dropping out. I am still getting a huge amount of DNS resolution failures too even though I am using Cloudflare DNS servers.....

My service dropped a minimum of 6 times yesterday throughout the day

Hi mitchgixer6

I'm really sorry to hear this.

Would you like me to send a replacement router for testing?

[mitchgixer6]

I think I will try using a different DNS provider before trying another router again.....

Hi Bob 

Thanks so much for this information, very helpful and insightful.

I'm currently trying to get a loan of another router to do more testing. It certainly seems strange to me, unexplained dropouts are never good or welcome!

Fingers crossed this isn't an issue that may be long standing for both of us.....

Hi Mitchgixer6 - your issue seems to be common else where . I have similar router stats showing DNS failures and router disconnection going back to Friday of last week and the sudden disconnects are very frustrating. This is not your kit but network/internet issues. TT has a history of poor DNS server issues and recently claimed that they were building a new DNS server but had no in service date. Also with the Queens funeral etc |I suspect that many servers are overloaded and suffering outrages. This might get better on Tuesday when HMQ is laid to rest . Mine seem to have stabilised today with no outages since early this morning.

Hi again

Unfortunatley it looks like I may have spoken too soon, I have just experienced multiple drop outs. I have a feeling it was these drop outs that affected my line speed via the DLM in the beginning. I am also still seeing multiple DNS name resolution failures which are only happening with my TALKTALK router. I managed to borrow a TP Link router for a few days this week to see if it helped with my speed. It didn't but I didn't see any DNS errors in the logs for that router.

Hi mitchgixer6

I'm so glad to hear this, thanks for letting us know.

I will check in again with you next week just to make sure everything is still working ok.

Thanks again.

Debbie 🙂

[mitchgixer6]

Hi Debbie 

The Engineer has just visited and the problem seems to be sorted. I'll keep an eye on my speeds for the next week or so just to make sure they are stable again. 

Thanks again for the help 

[Debbie-TalkTalk]

Hi mitchgixer6

Thanks for confirming your details.

I have arranged the Openreach engineer visit for Friday 16/09 AM (8am - 1pm)

Please let us know how you get on following this visit.

Thanks again.

Debbie

[Chris-TalkTalk]

Hi mitchgixer6,

thanks for answering the security questions, I've sent you a PM requesting a little more information 

Chris

[Chris-TalkTalk]

Hi mitchgixer6,

I've replied to your PM

Chris

[Chris-TalkTalk]

Well it's really up to you as there's a potential charge but if you've tested at the test socket then the only option we really have is to have an engineer check the line for potential causes of the drop in speed.

Chris

[mitchgixer6]

OK, so would you recommend going ahead with an engineer visit? 

[Chris-TalkTalk]

The expected speeds showing now on the website just reflect the current sync speed. Your speed hasn't been reduced on purpose and as it's so much lower than the the guaranteed minimum when you signed up then there could be a line fault.

Chris

[mitchgixer6]

OK, appreciate that. What does this actually mean though? Does the this negate the requirement for an engineer visit? Has my speed been reduced on purpose or is this lower speed still a symptom of a fault somewhere? 

[Chris-TalkTalk]

The current speed offered will be affected by your current sync speed. As your current sync speed is below the guaranteed minimum at the time that you took the contract them we can raise this for investigation.

Chris

[mitchgixer6]

OK thanks for clearing this up.

I was wondering if you would be able to check the speed available to my address? I had a look on the TalkTalk website as if I was a new customer. The guranteed speed offered on Fibre 65 (which is my current plan) is 21-23 Mbps. Is this correct?
