DNS issues #10911

Open rowleya opened 1 week ago

rowleya commented 1 week ago

Description

We seem to periodically get issues resolving web sites on some run runs. This appears completely random on different operating systems, though it appears to be almost constant on macOS and less often on Ubuntu and very infrequently on Windows.

Platforms affected

Runner images affected

Image version and build link

On Ubuntu 22.04, last encountered: 20241015.1.0 (https://github.com/SpiNNakerManchester/sPyNNaker/actions/runs/11700388899/job/32584448086) On Windows Server 2022, last encountered: 20241021.1.0 (https://github.com/SpiNNakerManchester/sPyNNaker/actions/runs/11660030018/job/32462691344) On MacOS 14 Arm64, last encountered (note this run is disabled now as it happens so often): 20240818.4 (https://github.com/SpiNNakerManchester/sPyNNaker/actions/runs/10593826135/job/29357835356)

Is it regression?

Not obvious - possibly not

Expected behavior

DNS lookup succeeds on every run!

Actual behavior

DNS lookup fails randomly.

Repro steps

Run actions; could probably re-run some of our actions as linked above, but it is random...

Hi @rowleya , It seems to be that the issue you’re experiencing might be related to the DNS configuration for the domain spinnaker.cs.man.ac.uk, rather than an issue with the macOS latest environment itself. Sometimes, DNS misconfigurations or issues on the DNS server side can cause the problems. Could you please check on your end to ensure there are no DNS related issues? We’re also looking into it from our side to confirm there are no additional factors involved.
