Recently, Maxar has seen sharp usage increases through automated requests coming from a few areas of the world that are of concern. These are having detrimental impacts to our service and we are taking measures mitigate. Unfortunately this will mean an interruption of our imagery services for OpenStreetMap. Soon we will suspend our imagery service, and we are working with the developers of OSM editing tools to implement a more secure service and restore full access to the Maxar Standard and Premium layers as soon as possible.
Thank you for your understanding and we look forward to solving this problem together.
