Title: Is anyone else having slow dns problems?
Post by: Bowdon on November 14, 2019, 12:09:07 PM
A lot of sites keep timing out and the addresses show its not just non-UK sites either.

This is the site of my local newspaper and it won't connect: https://www.oldham-chronicle.co.uk (https://www.oldham-chronicle.co.uk)

I'm using the BT Hub at the moment. But I have the computer dns set googles dns server; 8.8.4.4 and 8.8.8.8

I get slow response on my work laptop, but I can guarantee it's nothing to do with DNS by itself, there's other "reasons" :)

Ahh, glad it wasn't just me lol. I checked there earlier but nobody was talking about it.

Apparently it effected other isp's and vm too.

First I suggest cloudflare dns over google ip is 1.1.1.1 for ipv4.  They dont log queries (at least not tied to requesting ip).  Plus in my opinion its faster and they support dns over tls.

Second try to use a dns server like unbound that supports a setting called "serve expired" as your caching server, basically it will keep the most recently fetched record response cached forever until a new query is requested, and then it will only do a background update not making the live query wait for it.  Its a game changer in this era of very low ttl dns records.

If you have no lan caching server, then get one set up. ;)
