- There is an outage on Castor announced for Thursday (1st March) while the database systems have Oracle patches applied.
- The IPv6 connections, both to the RAL Core network and the 'bypass' route were moved to share the IPv4 connections was completed successfully. This was done ahead of a change to enable IPv6 (dual stack) on the Echo Gateways (scheduled for the 27th).
- AliceDisk is getting very full. Alice have been in informed and we continue to monitor.
Current operational status and issues

- The problems with data flows through the site firewall being restricted is still present. New firewall kit has be purchased and delivered, awaiting deployment.
