You can view the current version of this document on the [Google maintenance policy for Looker-hosted services](/looker/docs/google-maintenance-policy-for-looker-hosted-services) documentation page.\n\nDuring 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.\n\nOn rare occasions, urgent service outside of the standing maintenance hours may need to be performed. A [Technical Contact](/looker/docs/admin-panel-general-settings#technical_contacts) may also schedule updates, server upgrades, restarts, or other maintenance outside of the following hours.\n\nRegular maintenance and Looker updates\n--------------------------------------\n\n### Hosts in the Americas\n\n### Hosts in Europe, the Middle East, and Africa (EMEA)\n\n### Hosts in Asia and the Pacific (APAC)\n\nUrgent maintenance\n------------------\n\n### Hosts in the Americas\n\n### Hosts in Europe, the Middle East, and Africa (EMEA)\n\n### Hosts in Asia and the Pacific (APAC)"]]
