<li>I switched CGSpace to Node.js v20 since I’ve been using it in dev and test for months</li>
</ul>
<h2 id="2024-11-18">2024-11-18</h2>
<ul>
<li>I see a bot (188.34.177.10) on Hetzner has made 35,000 requests this morning and is pretending to be Googlebot, GoogleOther, etc
<ul>
<li>Google publishes their range of IPs also: <a href="https://developers.google.com/search/docs/crawling-indexing/verifying-googlebot">https://developers.google.com/search/docs/crawling-indexing/verifying-googlebot</a></li>
<li>Our nginx config doesn’t rate limit the API but perhaps that needs to change…</li>
<li>In DSpace 4/5/6 the API was separate from the user interface so we didn’t need to enforce rate limits there because we encouraged using that over scraping the UI</li>
<li>In DSpace 7 the API is used by the frontend and perhaps should have the same IP- and UA-based rate limiting</li>
</ul>
</li>
</ul>
<h2 id="2024-11-19">2024-11-19</h2>
<ul>
<li>I notice 10,000 requests by a new bot yesterday:</li>

<li>Seems to be some kind of PHP framework library</li>
<li>Yesterday one IP in Argentina made nearly 1,000,000 requests using a normal user agent: 181.4.143.40</li>
<li>188.34.177.10 ended up making 700,000 requests using various Googlebot, GoogleOther, and even normal Chrome user agents</li>
