Re: Virgin Akamai Cache Congestion
So I’m still using VMs DNS. If I set my router to my NAS (which is synology/docker/adguard now) my internet dies. Wondering if it was due to running pihole in docker (have since deleted the container) and a port conflict, however the instance is set to use my nas ip.

Re: Virgin Akamai Cache Congestion
why don't you tell your router to use Google dns? (or cloudfare/whatever your preference is)
|
Re: Virgin Akamai Cache Congestion
Because as per synthetics evidence, changing dns provider kills quality on things like Nowtv/btsport. I haven’t tried google dns but I think synthetic had.
|
Re: Virgin Akamai Cache Congestion
Yeah it doesnt matter which you use if you dont have DOH/DoT
|
Re: Virgin Akamai Cache Congestion
Synthetic - have you managed to fully resolve the issue using DoT or DoH for both BT and Now?

Re: Virgin Akamai Cache Congestion
So when I had adguard running, I set my windows pc to my DNS server - however I still experienced issues with now and bt. Bit frustrating really. I’ll try again when I can get my router/dns server playing nicely.

Re: Virgin Akamai Cache Congestion
I can't see how "pure" DNS would affect routing as all it does is translate name to IP (and back maybe). If different DNS's resolve differently that may affect things.
You could try the tracepath command which works a little bit differently and doesn't need root privileges on UNIX/LINUX. This can show if packets are fragmented and highlight asymmetric routing though the latter isn't always the problem it used to be. |

BT sport ultimate - constant buffering and unwatchable BT SPORT HD - really bad quality with buffering, just less than ultimate Nowtv - buffering and really poor quality As soon as I revert to VM dns it’s fine |
Re: Virgin Akamai Cache Congestion
Not the best solution but do an nslookup / dig using the virgin servers, then set a static dns in your pihole for that akamai domain so when you're using CF/google, your pihole will send you to the ones you use when you're using the virgin DNS
Or i guess use virgin's DNS if you're not having any trouble with them :) |

I've noticed a bit of latency recently, although I've not correlated it to any particular site or route, and I was, unfortunately, dealing with another issue on my MBP that saw seeing my downloads capped to 20Mbit/s, I stumbled across the solution for that by accident though.
I just ran a trace to the akamai server that was mentioned in this thread. https://www.cableforum.uk/board/atta...3&d=1624725485 MOD EDIT - too large image removed and replaced with smaller image. |
Re: Virgin Akamai Cache Congestion
So if i use google DNS it sends me to the virgin cache, and everything appear to works as it should now, i wonder if virgin have fixed their mess..
1.1.1.1 still sends me via cogento though |
Re: Virgin Akamai Cache Congestion
I dont watch any terrestrial tv apart from Wimbledon every year. Yesterday i had the tennis going on my tvs, tablet and phone simultaneously using iplayer and google dns and didnt have any problems.
