The failures are not blocking clean CI because they are happening only occasionally. First failure I could find happened on 9th of January (https://dev.azure.com/dnceng-public/public/_build/results?buildId=519103) and last so far on 28th of April (https://dev.azure.com/dnceng-public/public/_build/results?buildId=658560&view=results).

No longer failing, closing.
