We are pleased to publish the third Sentinel Data Access Annual Report. This 2017 report takes up from where the 2016 report left off, and analyses the uptake of Copernicus Sentinel data and the performance of the Sentinel Data Access System during the period 1 December 2016 to 30 November 2017.

By the end of the reporting period, the Sentinel Data Access System was supporting 109,690 registered users, a daily publication rate of 10.04TB/day, and an average daily download volume of 93.5TB. A total of 50,964,670 products had been downloaded by users since the start of data access operations, with a total data volume of 41.35 PB. As well as providing detailed statistics behind these figures, the report explains the challenges and the solutions found by the the Data Access Operations team in publishing and disseminating such huge volumes of data.

The 2017 Sentinel Data Access Annual Report is available here.

A routine decontamination activity of the Sentinel-2B MSI is planned to take place over a continuous period of 24-hours between 26 and 27 May, from 18:00 to 18:00 UTC (corresponding to the period between absolute orbits 6373 to 6387). During this temporal window, no MSI acquisition will take place.
Correlated calibration activities will be performed around the decontamination period which will affect the nominal acquisition plan even further between 26 and 28 May from 07:00 to 09:30 UTC.

As a consequence of a ground segment anomaly occurred on Saturday 05 May in the evening and solved on Monday 07 May in the morning, the availability in the Data Hubs of some of Sentinel-2 products with sensing date within this time window is delayed.
The recovery of the missing products has been started and is expected to be completed by this week.
We apologise for any inconvenience this may cause.

Report update of 13 June 2016:
It is highlighted that further to the initial announcement of 07 May above, the availability for data acquired on 08 and 09 May has been affected by the recovery process and nominal dissemination performance was recovered only on 09 May around midday, while the recovery of the whole set of delayed products between 05 and 09 May has been completed on 12 May.

Due to a ground segment anomaly, the availability of Sentinel-2 L1C products was delayed in the data hubs on 29 April 2018.

We have taken actions to resolve this issue and the nominal flow has been resumed.

We apologise for the inconvenience this may have caused.

The Sentinel-1 Level-1 products acquired between 21 and 22 of March 2018 and between 8 and 11 of April 2018 have been processed without Restituted Orbit Files (AUX_RESORB) and are subject to the following quality disclaimers:

A new version of these products will be gradually published in the next days. The original products (as listed in the corresponding quality disclaimer) will be removed from the on-line data access only when the new version has been published.

Users are informed that the incident on the Data Hub infrastructure started at 9:30 UTC (24 April 2018) has been resolved at 14:15 UTC (24 April 2018).
The incident was triggered by the combination of a problem on the switches interconnecting the servers to the storage and by the fault of the switches failover mechanism. The problems have been identified and fixed.
The services downtime lasted for about 4 hours and 45 minutes.
Products publication flows are back to nominal on all data dissemination services.
We apologies for the inconvenience this may have caused to your activities.
