- I found a few more IPs making requests using the shady Chrome 44 user agent in the last few days so I will add them to the block list too:
- 18.207.136.176
- 185.189.36.248
- 50.118.223.78
- 52.70.76.123
- 3.236.10.11
- Looking at the Solr statistics for 2022-04
- 52.191.137.59 is Microsoft, but they are using a normal user agent and making tens of thousands of requests
- 64.39.98.62 is owned by Qualys, and all their requests are probing for /etc/passwd etc
- 185.192.69.15 is in the Netherlands and is using a normal user agent, but making excessive automated HTTP requests to paths forbidden in robots.txt
- 157.55.39.159 is owned by Microsoft and identifies as bingbot so I don’t know why its requests were logged in Solr
- 52.233.67.176 is owned by Microsoft and uses a normal user agent, but making excessive automated HTTP requests
- 157.55.39.144 is owned by Microsoft and uses a normal user agent, but making excessive automated HTTP requests
- 207.46.13.177 is owned by Microsoft and identifies as bingbot so I don’t know why its requests were logged in Solr
- If I query Solr for
time:2022-04* AND dns:*msnbot* AND dns:*.msn.com. I see a handful of IPs that made 41,000 requests
- I purged 93,974 hits from these IPs using my
check-spider-ip-hits.sh script
- Now looking at the Solr statistics by user agent I see:

- I purged 2,900 hits from these user agents from Solr using my
check-spider-hits.sh script
- I made a pull request to COUNTER-Robots for some of these agents
- In the mean time I will add them to our local overrides in DSpace
