Due to a Ground Segment anomaly on 9 February 2018, NRT/NTC/STC user data could be degraded or missing in the following time interval:

• SRAL: products from sensing time 13:43:24 to 14:13:24 UTC on 9 February (absolute orbit 10321, relative orbit 338 of cycle 27)

Due to a ground segment anomaly on 07 February 2018, NRT/NTC/STC user data could be degraded or missing during the following time interval:

• SRAL: products from sensing time 14:24:45 to 14:34:44 UTC on 7 February (absolute orbit 10293, relative orbit 310 of cycle 27)

The Sentinel-3A ground segment anomaly on 10 February 2018 has now been solved.
Following the resolution, SRAL STC L2 products starting from 00:30 UTC on 10 February have been delayed.
Nominal production has been restored for products starting from 05:08 UTC sensing time on 11 February.

Due to a Sentinel-3A ground segment anomaly on 10 February 2018 the following products are affected:

• SRAL NRT products generated starting from 12:00 UTC on 11 February (creation date and time) could be degraded
  
• SRAL STC L1/L2 products sensed starting from 00:30 UTC on 10 February (sensing date and time) will be delayed until further notice
  

Investigation is ongoing.

Users are informed that the availability of the Sentinel-2 products in the data hubs is delayed as of 05 February 2018.

Based on the current analysis at the ground segment level, such delay would be linked to the ongoing maintenance on DHuS infrastructure, resulting in the degraded performances of Sentinel-2 products dissemination to data hubs. There has been an ongoing investigation on the network side to fix this issue as soon as possible.

We apologise for any inconvenience this may cause.

Due to a Sentinel-3A ground segment anomaly on 05 February 2018, now resolved, NRT products from orbit #10259 to #10261 have been delayed; nominal production was fully restored starting from orbit #10262.

Following the News 00170 published on the 22th of January, users are informed that the decontamination activity of the Sentinel-2A MSI has been successfully completed.
Sentinel-2A has now resumed nominal operations since 05 February 2018 08:00 UTC.

Due to a Sentinel-3A ground segment anomaly on 05 February 2018, NRT products from orbit #10258 could be delayed.
Investigation of the issue is ongoing.

Sentinel-1A was unavailable on 2 February 2018 from 14:27 to 16:14 UTC, due to a SAR anomaly. No data were generated during this period.

A set of service infrastructure upgrades are scheduled from 07:00 UTC of the 5th of February 2018 to 18:30 UTC of the 6th of February 2018.
No downtimes are foreseen but the performances of the following Data Hub services might be affected:

• Copernicus Open Access Hub (also including API Hub and the Sentinel-3A Pre-operations Data Hub)
  
• Collaborative Data Hub - Node 1
  
• Copernicus Services Data Hub
  

We apologize for any inconvenience this might cause.

Due to an on-board anomaly on 20 January 2018, NRT/NTC/STC user data could be degraded or missing in the following time interval:

• SRAL: user products impacted from sensing time 2018-01-20 08:50:51 UTC to 2018-01-20 09:00:51 UTC (absolute orbit 10033, relative orbit 50 of cycle 27)

Following the news previously published, Data Hub users are informed that the network link has been restored to its nominal performances.

The anomaly affected the download performances of ColHub Node 1 from 09:00 UTC to 16:00 UTC of Friday, 26 January 2018. The delay on the products publication on ColHub Node 2 has been also solved.

We apologise for the inconvenience caused.

Today, the 26th January 2018, ColHub Node 1 is experiencing a significant drop in network performances that are leading to very slow download times for the Sentinel Data products. User experience in this period is severely impacted.
The anomaly is under investigation with the network provider, to be resolved as soon as possible.
Download rates on ColHub Node 2 are nominal but there is a temporary publication delay of the new products.

Our apologies for the inconvenience.

The Sentinel-3A ground segment anomaly on 23 January 2018 has now been resolved, but NRT products and SRAL STC products from orbit 10077 to 10080 are missing.

Due to a Sentinel-3A ground segment anomaly on 23 January 2018, NRT products from orbit #10077 are missing.
Investigation of the issue is ongoing.

A routine decontamination activity of the Sentinel-2A MSI is planned over a continuous period of roughly 24-hours between 07:10 03 February 2018 and 06:20 04 February 2018 UTC (corresponding approximately to between absolute orbits 13674 to 13687).

During this time window no MSI acquisition will take place.

Correlated calibration activities will be performed around the decontamination period that will further affect the nominal acquisition plan between 07:20 02 February 2018 and 08:00 05 February 2018 UTC.

Due to a Sentinel-3A Ground Segment anomaly on 14 January, the following SRAL Level-1/Level-2 products are delayed:

• STC products acquired from 23:43 UTC on 11-01-2018 to 00:31 UTC on 14-01-2018
  
• NTC products acquired from 23:08 UTC on 18-12-2017 to 22:47 UTC on 21-12-2017

In preparation for the next set of service infrastructure upgrades a set of maintenance activities are scheduled on:

• Tuesday, 23 January 2018
  
• Tuesday, 30 January 2018
  
• Wednesday, 31 January 2018
  

The maintenance will affect the Data Hub services according to the following programme:

Tuesday, 23 January 2018 from 07:00 UTC to 18:30 UTC
During the maintenance window the following Data Hub services will be unavailable:

• Copernicus Open Access Hub (also including API Hub and the Sentinel-3A Pre-operations Data Hub)
  
• Collaborative Data Hub - Node 1
  
• Copernicus Services Data Hub
  

The International Access Hub and the Collaborative Data Hub Node 2 will be available for queries and downloads, however the publication of new products will be suspended for the duration of the maintenance. The publication of the Sentinel-1 NRT products will be instead nominal.

30 and 31 January 2018 from 07:00 UTC
During the maintenance window it is expected a performance degradation on the search and download functions.
The following Data Hub services will be affected:

• Copernicus Open Access Hub (also including API Hub and the Sentinel-3A Pre-operations Data Hub)
  
• Collaborative Data Hub - Node 1
  
• Copernicus Services Data Hub
  
  

The publication of new products will be temporarily delayed for all Sentinel missions.
We apologize for any inconvenience caused.

Collaborative users are informed that a maintenance activity on ColHub Node 2 is planned on Thursday, 18 January 2018. During the maintenance window the access Node 2 will be unavailable from 10:00 CET to 14:00 CET.
The access Node 1 will not be affected by the maintenance and available to the users for queries and downloads.
We apologize for the inconvenience that this may cause.

Due to a Sentinel-3A Ground Segment anomaly, SRAL Level-1/Level-2 Short Time Critical (STC) products could be missing or delayed from 12 January 2018 at 21:00 UTC to 15 January 2018 at 21:00 UTC sensing time.
