Thank you!
I've been struggling with this for a week before I realised what the issue was, I've just checked and it is fixed now.
Thank goodness I wasn't going mad.

Yeah, but I was seeing DNS lookup failures, it was making browsing the web almost impossible. I worked back from the DNS failures to ping and not the other way around, it still could have been a false positive but with both seemingly confirming a packet loss I figured there was an issue.
I'm the author of Pingnoo
https://github.com/fizzyade/pingnoo so understand why ping may not be a useful metric unless you know what you're doing.
I may now add a DNS lookup module into Pingnoo to check for actual losses during lookup.
