Regular maintenance and Looker updates
During the regular maintenance times, your instance may be temporarily unavailable for updates, server upgrades, or other system work. Looker takes system availability seriously and makes every effort to keep any interruption brief and to these scheduled hours. We try to avoid performing any system-related work on Friday and through the weekend to ensure that someone is available to respond to unanticipated issues.
On rare occasions, urgent service outside of the standing maintenance hours may need to be performed. A Technical Contact may also schedule updates, server upgrades, restarts, or other maintenance outside of the following hours.
