DNS issues again? (intermittent)

[#1]

Unsure if this is affecting multiple users but it seems the DNS servers are failing over the last 30 mins. Have tried on multiple machines and can replicate the issue. I am able to reach addresses using IP addresses but cannot resolve site names using the plusnet DNS settings.
This seems to come and go. I rebooted my router but still having the same issues and so changed my DNS settings over to use 8.8.8.8/8.8.4.4. Is anyone else having the same issues?

Not seeing any dns issues here.
Have you tried switching gateway?

All i did was redirect the DNS to google's and that seemed to fix the issue. I also have another line here with another ISP and everythings working fine on that one. Ill change my DNS back soon and see if its working again.

I'm seeing a little elevation of figures on my connection. pcl-ag03.

I've been having a few issues to actually, but I was unsure if it's my connection, as sunce changing to fibre it's been, well not that clever.
But looking at my Sam Knows graph, and seeing this thread, I think this could be part of my problem.
