- Skype with Michael Victor about CKM and CGSpace
- Discuss the new IITA research theme field with Abenet and decide that we should use `cg.identifier.iitatheme`
- This morning there was another alert from Linode about the high load on CGSpace (linode18), here are the top IPs in the web server logs before, during, and after that time:
```
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "04/Feb/2019:0(5|6|7|8|9)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

889 35.237.175.180
1332 34.218.226.147

4311 45.5.184.2
4658 205.186.128.185
4658 70.32.83.92
```
- At this rate I think I just need to stop paying attention to these alerts—DSpace gets thrashed when people use the APIs properly and there's nothing we can do to improve REST API performance!
- Perhaps I just need to keep increasing the Linode alert threshold (currently 300%) for this host?
