By ArcGIS Content Team

The Esri ArcGIS Online Basemap system (i.e., services.arcgisonline.com, server.arcgisonline.com) will be upgraded from ArcGIS 10.2 for Server to ArcGIS 10.3 for Server on Tuesday June 9. The update will improve system stability and performance, with no known issues at this time. We are planning no disruption of service during the upgrade.
