Since Dec 4th, I'm seeing an increase in errors that seem to be caused by Saucelabs. Tests were fine before that date, or at least failures were plausible. But recently more and more errors of the kind of "Sauce could not start your job." start popping up. Strangely there are days where this error does not happen, while on another day it is happening several times per build.
E.g. December 10th seemed to be a bad day for Saucelabs.
Looks like the tests are failing randomly :(
