Thursday 23th of May between 10:30 and 11:30 UTC we will be running a test jointly with STFC for the new implemented load-balancing between different ESGF nodes.
Please notice that during the test new components will be activated and some requests to CMIP5 data might fail.
Once this new functionality is in place access to data hosted in ESGF nodes through the CDS it is expected to be more reliable.
Thanks
