- Also, I notice they ended up registering a Handle (they had been considering taking KnowledgeArc's advice to *not* use Handles!)
- Did some coordination work on the hotel bookings for the January AReS workshop in Amman
## 2018-12-17
- Linode alerted me twice today that the load on CGSpace (linode18) was very high
- Looking at the nginx logs I see a few new IPs in the top 10:
```
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "17/Dec/2018" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

6706 94.71.244.172
```
- `94.71.244.172` and `143.233.227.216` are both in Greece and use the following user agent:
```
Mozilla/3.0 (compatible; Indy Library)
```
- I see that I added this bot to the Tomcat Crawler Session Manager valve in 2017-12 so its XMLUI sessions are getting re-used
- `2a01:4f8:173:1e85::2` is some new bot called `BLEXBot/1.0` which should be matching the existing "bot" pattern in the Tomcat Crawler Session Manager regex
