DNS Issues?

Been having problems connecting to websites today yet the internet connection appeared to be up, I eventually tried changing the DNS on my computer from DHCP to take static addresses and put the Google Public DNS server ip addresses in ( 8.8.8.8 and 8.8.4.4 ) and can access webpages ok again.
So either there's DNS issues or the router is having a bad day?

Something I have noticed, is that the DNS answer packets are no longer being prioritised above normal web traffic, they now are being given the same prioritisation as general web traffic.

You can change the DNS settings on the Technicolor router that PlusNet supply but you have to use telnet to do it - just google "technicolor dns settings" and you'll find instructions on how to do it.
I've added the google public dns servers on a lower metric to the plusnet ones which means the router will forward dns requests to the public servers before the plusnet ones and it seems to work ok.
It helps that I'm used to doing stuff like this as I work in IT but I hate to think what people with no experience of this will be going through - I did notice PlusNet's support stats showed their call times were high last night. I don't fancy waiting an average of 30 minutes on hold in a queue of 49 people!

Quote from: CJBlue I've found that since changing to using a public DNS server that webpages I couldn't get to yesterday are working now
Yes, this is the thing I don't understand, i'm not a technical person but I do understand the basic principles of fault finding. Something not working, changed a thing, now working = the thing was the issue.
Why then do Plusnet repeatedly state that there isn't an issue with their DNS servers.
I've looked at changing the DNS in the router, the Telnet requirement doesn't look too straightforward to me, it took me a fair bit of research to discover how to enable Telnet in WIN10, and once I had managed that I got a case of the fears about disabling my router completely and chickened out....!!

I'm not aware of any widespread issues and there's not a lot to go on in this thread.

All websites are slow to open. I see the little circle spinning for ages and then the page loads. If I click a link then same again.

This seems fine. Yet pages are taking ages to load and games cannot connect to the login servers. I don't have any tracing software. I'm not an IT expert.

So your problem is probably the Technicolor 198.18.1. IP address issue. Either you can apply the config change described here or get Plusnet to do it remotely for you. Or you could configure your computer to use the Plusnet DNS servers (212.159.6.9 and 212.159.6.10) directly, bypassing the DNS server in the router.
