we are about to upgrade the kubernetes version that runs PAWS, from 1.6 to 1.17.
We don't expect any interruptions major on the service, perhaps only some
hiccups when pods are restarted/rescheduled.
More information is available in this phabricator ticket:
The operation may take something between 30 minutes and 1 hours, and we are
starting soon after I finish sending this email.
Please, ping us if you see anything wrong.
