Thanks Chris for checking this,

Indeed it seems that there is a timeout of 30s that seems enough to
cause the tests to fail around 5% of the times.  I also note that
some of the failures were synchronised on some architecture (like
failing on the same day in amd64 and arm64), so it may be network
issues that are not solvable by changing the timeout.

Indeed, the failure rate on risc64 is way higher than on other release
architectures.  The tests run also 10 times slower, which is a lot.  I
am not familiar with risc64, but if the usage pattern of this
architecture is narrower than amd64 and arm64 and does not include
scientific computing, it may make sense to just remove all
team-maintained r-cran-* packages there too, as it is not supported
upstream.  Risc64 users who just want to perform HTTP requests with a
script language have better alternatives such as Perl or Python.

Have a nice day,

Charles
