    - cg.identifier.ccafsprojectpii
    - cg.subject.cifor
  - For now we will keep them in the search filters
+- I modified my `check-duplicates.py` script a bit to fix a logic error for deleted items and add similarity scores from spacy (see: https://stackoverflow.com/questions/8897593/how-to-compute-the-similarity-between-two-text-documents)
+  - I want to use this with the MARLO innovation reports, to find related publications and working papers on CGSpace
+  - I am curious to see how the similarity scores compare to those from trgm... perhaps we don't need them actually
+- Deploy latest changes to submission form, Discovery, and browse on CGSpace
+  - Also run all system updates and reboot the host
+- Fix 152 `dcterms.relation` that are using "cgspace.cgiar.org" links instead of handles:
+
+```console
+UPDATE metadatavalue SET text_value = REGEXP_REPLACE(text_value, '.*cgspace\.cgiar\.org/handle/(\d+/\d+)$', 'https://hdl.handle.net/\1') WHERE dspace_object_id IN (SELECT uuid FROM item) AND metadata_field_id=180 AND text_value ~ 'cgspace\.cgiar\.org/handle/\d+/\d+$';
+```
+
+## 2022-07-10
+
+- UptimeRobot says that CGSpace is down
+  - I see high load around 22, high CPU around 800%
+  - Doesn't seem to be a lot of unique IPs:
+
+```console
+# awk '{print $1}' /var/log/nginx/{access,library-access,oai,rest}.log | sort -u | wc -l
+2243
+```
+
+Looking at the top twenty I see some usual IPs, but some new ones on Hetzner that are using many DSpace sessions:
+
+```console
+$ grep 65.109.2.97 dspace.log.2022-07-10 | grep -oE 'session_id=[A-Z0-9]{32}:ip_addr=' | sort | uniq | wc -l

+- These IPs are using normal-looking user agents:

+
+- I will add networks I'm seeing now to nginx's bot-networks.conf for now (not all of Hetzner) and purge the hits later:
+  - 65.108.0.0/16
+  - 65.21.0.0/16

+  - 135.181.0.0/16
+  - 138.201.0.0/16
+
+- I think I'm going to get to a point where I categorize all commercial subnets as bots by default and then whitelist those we need
+- Sheesh, there are a bunch more IPv6 addresses also on Hetzner:

+
+- Maybe it's time I ban all of Hetzner... sheesh.
+- I left for a few hours and the server was going up and down the whole time, still very high CPU and database when I got back
+
+![CPU day](/cgspace-notes/2022/07/cpu-day.png)
+
+- I am not sure what's going on
+  - I extracted all the IPs and used `resolve-addresses-geoip2.py` to analyze them and extract all the Hetzner networks and block them
+  - It's 181 IPs on Hetzner...
+- I rebooted the server to see if it was just some stuck locks in PostgreSQL...
+- The load is still higher than I would expect, and after a few more hours I see more Hetzner IPs coming through? Two more subnets to block
+- Start a harvest on AReS
+
+## 2022-07-12
+
+- Update an incorrect ORCID identifier for Alliance
