No.  That report reflects a networking problem internal to the colo.
But the colo's internal networking is completely reliable.[1]

I investigated, and the host that job run on, italia0, has some kind
of Problem:
  http://logs.test-lab.xenproject.org/osstest/results/host/italia0.html

Meanwhile italia1 has been out of service due to a PDU fault, and we
were working on recomissioning it.  I have unblessed itaila0 and asked
Credativ to investigate.
