 - For what it's worth, there are no errors on any other recent days, so it must have been some network issue on Linode or CGNET's LDAP server
 - Linode emailed to say that linode578611 (DSpace Test) needs to migrate to a new host for a security update so I initiated the migration immediately rather than waiting for the scheduled time in two weeks

+- Twice in the last twenty-four hours Linode has alerted about high CPU usage on CGSpace (linode2533629)
+- Communicate with Sam from the CGIAR System Organization about some broken links coming from their CGIAR Library domain to CGSpace
+- The first is a link to a browse page that should be handled better in nginx:
+
+```
+http://library.cgiar.org/browse?value=Intellectual%20Assets%20Reports&type=subject → https://cgspace.cgiar.org/browse?value=Intellectual%20Assets%20Reports&type=subject
+```
+
+- We'll need to check for browse links and handle them properly, including swapping the `subject` parameter for `systemsubject` (which doesn't exist in Discovery yet, but we'll need to add it) as we have moved their poorly curated subjects from `dc.subject` to `cg.subject.system`
+- The second link was a direct link to a bitstream which has broken due to the sequence being updated, so I told him he should link to the handle of the item instead
