Those query times are absolutely insane.

Hey, if you do a +trace for any of those domains, does the resolution of the intermediate names take as long as this? Like so:

$ dig a in cycle.travel +trace

I'll try next time.
When connected to VPN and the issue happens I generally browse to a web site I use a lot before anything else and that invariably responds quickly and immediately; domain name almost certainly previously resolved and cached as I try on a site I use all the time (e.g. UK MetOffice). Moment I switch to ISP (disconnect from VPN) it immediately works (i.e. onto ISP's DNS.

Use your router IP and serve DNS over the connected server on your flashed router. Internal DNS vs. External/Global DNS.

Afraid that means nothing to me. I don't have a flashed router, I use a Mac, I don't have a lot of what that document is talking about. In English? None of the linked document seems to apply so I'm lost.

Hello everybody,

can you please re-perform all of your tests and report back? We have found a bug which potentially might have caused the reported names resolution failures under rare circumstances on a few servers. We have fixed the code. Please let us know whether the problems keeps occurring or not, as our automated DNS testing sentinels deployed on the reported flag servers have stopped reporting resolution failures since when the fix was deployed. A couple of hours ago the fix has been deployed.


Kind regards

Hello!

Since no reports came in here or in tickets in the last 10 days we consider the problem as resolved, thank you very much!
