BT & plus net DNS servers no longer resolving gmail.com

technonath — Thu, 21 Mar 2024 12:55:51 GMT

I am no longer a plusnet customer, but at work we use BT internet and I can see from twitter that it is also affecting plusnet customers too, so I have posted here in slight chance that someone techy from plusnet can actually escalate it to someone who can get it fixed.

your DNS servers come back with non existent domain when searching for gmail.com since yesterday.

switching my dns to 8.8.8.8 it can be resolved normally.

Hi,

Is this still happening? If so which DNS IP addresses are you using? I've just checked all 8 of our DNS IPs and they all respond with something similar to this:

host gmail.com 212.159.6.10
Using domain server:
Name: 212.159.6.10
Address: 212.159.6.10#53
Aliases:

gmail.com has address 142.250.200.37
gmail.com has IPv6 address 2a00:1450:4009:820::2005
gmail.com mail is handled by 20 alt2.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 10 alt1.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 40 alt4.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 5 gmail-smtp-in.l.google.com.
gmail.com mail is handled by 30 alt3.gmail-smtp-in.l.google.com.

Thanks, glad that's working again. I've sent this thread and the links on to the DNS team to look at why it wasn't working.

@dave

Thank you for picking this up here. If you need to know the DNS server in use, I can post that when back home.
