Comment 37

[Kershaw Chang [:kershaw]]

The recent increase in failure rate is caused by bug 1916418.
The issue lies in HTTPSRecordResolver::OnLookupComplete, where I assumed that the DNS request for the HTTPS RR would always complete before the request for the CNAME, which isn’t always true. If the CNAME request finishes before the HTTPS RR request, the callback is invoked with null records.
