Superfast Speeds, slow websites - Help

TerrierHTFC · 21 Jun 2022 at 09:41

I've got BT full fibre 900 down 100 up, and if I run a speedtest this is more or less what I get. But for the last couple of weeks probably 50% of websites have been painfully slow to load, some can be upwards of 10 seconds, yet the same websites will load normally on my phone over wifi.

I've changed nothing hardware or settings wise. I've reset the router which did nothing. PC is connected via ethernet.

Any advice?

Try another DNS server, such as 9.9.9.9

Can you change the DNS settings on your router?

If so try using using a different DNS provider rather than the BT provided one e.g.

Google: Primary 8.8.8.8, Secondary 8.8.4.4
Quad9: 9.9.9.9, 149.112.112.112
Cloudflare: 1.1.1.1, 1.0.0.1

Changed it to the google ones you suggested and its instantly back to being as fast as it used to be, so many thanks!

Why would the default one suddenly have issues? Is this a BT problem?

Not necessarily a BT problem as such, but the BT servers likely aren't as high performing as dedicated servers as mentioned above.

If you care about privacy, then use Quad9 rather than Google. ISP DNS servers are generally rubbish.

FWIW I've never experienced slow loading of websites using the BT-provided DNS servers, so it's possible you're just masking a problem.
