GroupBy will be undergoing emergency maintenance on search services to mitigate an immediate risk to our infrastructure from 9:00 PM - 2:00 AM EDT tonight (August 1-2, 2018.) These changes may have a minimal impact of 1-2 dropped queries, which will return 400 errors. Search will be responsive on a retry. If you see any issues please contact us at email@example.com
for more details.
