Check regions
Uptime checks for HTTP, HTTPS, KEYWORD, API and GRAPHQL monitors can run from EU (Europe), US (United States) and ASIA (Asia Pacific); other monitor types run from EU. Set them with locations on monitor create and update. Screenshots for visual checks are taken in EU or ASIA (visualRegion).
Asia Pacific is enabled per workspace during its rollout. GET /api/monitoring/regions reports whether this workspace can use it. When it cannot, monitor create and update with ASIA return 400 with code REGION_UNAVAILABLE. A region outside your plan returns 403 with code LOCATION_RESTRICTED.
