Cloud UI
========

The web user interface of CrateDB Cloud is served from a single domain
`console.cratedb.cloud`_. The DNS record of this domain is a collection of
CNAME records with a geolocation routing policy. This means that traffic from
different parts of the world are statically routed to different regions where
the Cloud UI and the Cloud API are served from.

The routing default - in case the location of the user does not match with any
of the locations (continents) provided in the CNAME record - is
`bregenz.a1.cratedb.cloud`_.

Additionally to the global domain `console.cratedb.cloud`_ each region still
serves the UI and API from its region domain.
