Our operations team will be performing rolling maintenance on our Cloud Agent infrastructure beginning on Monday, January 29th at 09:00 UTC.
This rolling maintenance window is expected to run for approximately 72 hours. Regional timings for the maintenance can be found below:
2018-01-29 09:00 UTC to 2018-02-01 09:00 UTC
2018-01-29 04:00 EDT to 2018-02-01 04:00 EDT

During this rolling maintenance window, our teams will be applying patches to, and performing restarts of elements of our Cloud Agent Infrastructure.
While we do not expect significant disruption during this period, customers may notice missed data points on tests running from Cloud Agents while they are being updated. Our observations in a staging environment indicate a negligible performance impact - see below for charts showing equivalent systems operating against the same group of sites (Alexa Top 20 Sites):

This critical update is necessary and cannot be postponed, as it relates to Spectre and Meltdown vulnerability mitigation on our cloud agent infrastructure.
