Looks like Quad9 are having issues with their network since 14:00 , causing slow responses or timing out fully.

Nothing on their status page as yet and ticket sent in, edit 14:40: ticket replied to and now showing issue: https://uptime.quad9.net/incidents/k4snz9ywvdtv

Edit: 15:29 Quad9 are reporting issue resolved and resolution has gone back to normal.

Had reports from customers dotted around UK reporting the same issues.

Switching DNS providers fixes the issue.

Seems to have been on and off the last 2-3 days. It resolves eventually but certainly noticing delays in loading.
 
I had the same problem this morning with a few places complaining that "nothing is working". Switched them over to Cloudflare as a temporary fix.
 
Had a reply from support:

Code: 
Hello,
 
Thanks for reporting this issue.
 
Quad9 performed a major equipment refresh and compute upgrade in our London (LHR) PoP today, which required us to take our London PoP offline for several hours. As a result, some adjacent PoPs became overloaded and resulted in some service degradation.
 
Quad9 is now back online in London, and now with significantly increased compute that will enable us to serve the UK community for years to come in a performant and reliable manner.
 
Quad9 acknowledges that London/UK performance has been sub-optimal for some months, which prompted this major overhaul.
 
Quad9 is also in the process of deploying a secondary London PoP to increase our resiliency and service reliability in the coming weeks, further committing to our goal of serving the UK community in the long term.
 
We sincerely apologize for the performance and/or reliability issues experienced by the UK community during this event, and we're confident that the UK community can look forward to years of performant and stable Quad9 performance and reliability in the coming years.
 
If you're continuing to experience any issues, or if you feel this did not address your issue, please respond at your earliest and convenience, and we will aim to investigate immediately.

Looks like the issues with Quad9 started for me around ~1:40 PM and cleared up around 8:20 PM

As the UCG-Fibre was showing the following:

Got the same reply back over night from Zachary and sites that were still having issues are now resolved.

Will swap back to Quad9 at home tonight and see how I get on.
