An unexpected power outage occurred on Friday 22 March afternoon at the Svalbard ground station which significantly affected the nominal data reception capabilities for the Sentinel-1, -2, -3 and -5p satellites.
The power was restored relatively quickly, but a number of systems had been affected, requiring additional time for the station's operators to restore the nominal services.
The nominal availability of the products cascading from data acquisitions at Svalbard for these missions was critically affected in consequence, either irrecoverably, or subjected to long delays resulting due to the necessary reconfiguration work which had to be carried out at the station following the power loss.
The exhaustive list of the impacted datatakes is reported on the Copernicus Dashboard here, in association to the event reported on 22 March 2024.
It is further highlighted that the production associated with some of the delayed datatakes is still on-going and planned to be completed within the next couple of days.

We apologise for the inconvenience this may cause to your activities.

Following some issues we are investigating with the cloud provider, S2A and S2B publication delays may be observed on the Collaborative Nodes 2 and 3.

Here below the status of delay for each data product:
ColHub Node2
S2A L1C (about) 18 hours delay
S2A L2A (about) 6 hours delay
S2B L1C (about) 6 hours delay
S2B L2A (about) 18 hours delay
ColHub Node3
S2A L1C (about) 24 hours delay
S2A L2A (about) 18 hours delay
S2B L1C (about) 18 hours delay
S2B L2A (about) 24 hours delay

S1 and S3 backlog was recuperated and and publication of fresh data is now nominal on all Nodes.

Users are also informed that performances degradation and download problems have been experienced on Collaborative Node-1 since yesterday at 15:00 UTC.
Measures are in place to solve the problems.
