ECMWF will upgrade the version of the CCI1 backend powering part of the European Weather Cloud service at ECMWF between Monday 8 to Friday 12 July 2024, following the successful upgrade of the CCI2 Openstack backend.
Does it affect me?
EWC tenancies at ECMWF may live on either CCI1 or CCI2 backends. Those tenancies based on the CCI2 backend will not be affected by this update.
In Morpheus, you can see what backend is used in the name of the "cloud". Only resources in cloud named "ecmwf-cci1-..." may be affected.
What is the impact?
The upgrade should be transparent for most workloads on CCI1, as it will be done gradually across the infrastructure over three days to minimise disruption.
All going well, existing standard instances should not suffer any downtime. GPU-powered instances, however, will unfortunately need to be rebooted during the update.
Short interruptions to the APIs are expected, which means you may not be able to provision new instances during brief periods of time throughout the upgrade process.
