RAL Tier1 Operations Report for 4th June 2018
| Review of Issues during the week 28th May to the 4th June 2018.
|
- No incidents(major or minor), have been flagged during this reporting period.
| Current operational status and issues
|
- For the avoidance of doubt regards confusion over the status of both the BDii and Castor services. Tier-1 have NOT stopped or decommissioned these services. What has changed is that the Castor information stopped getting published in the BDii. This was due to a failure of the machine running the Castor Information Provide (CIP). The CIP was a legacy part of Castor (It didn't support GLUE2 schema), and was due to be decommissioned, the hardware failure expedited this issue. Although we admit this is not ideal, we decided against bringing back a service simply to then inform people we would shortly remove it.
