 Guaranteed service availability is facilitated through [https://eodc.eu/ EODC]’s [https://sentinels.copernicus.eu/web/sentinel/missions/sentinel-1 Sentinel-1] processing operations expertise, begun in 2014, which is regularly being assessed by the [https://http://www.esa.int/ ESA] mission reports. These ''lessons learned'' have been used to implement a completely independent IT infrastructure for the [https://emergency.copernicus.eu/ CEMS] [[INTRODUCTION | '''GFM''']] system operations.
 The operations is also organized through redundant '''24/7 production coordinator staff availabilities''', such that a '''99% service availability''' is guaranteed.
