The backlog in product publication on the SciHub and ApiHub, that has been noted in particular for Sentinel-2, has been significantly improved in recent weeks.
In order to stabilise the situation for the long term a new version of the data hub configuration will be transferred to operations in the next weeks, starting with the ApiHub. This new configuration provides further overall scalability and load balancing capability. The existing URLs are unchanged and the new version is backward compatible with the existing API.
During the initial operations it is possible that a slightly different data population may be noted for the latest data between two independent user sessions, an effect that will be minimised and should be effectively eliminated during the coming weeks through system tuning. The first downtime is planned for 23 November 2016.
