<h2 id="2022-08-13">2022-08-13</h2>
<ul>
<li>I noticed there was high load on CGSpace, around 9 or 10
<ul>
<li>Looking at the Munin graphs it seems to just be the last two hours or so, with a slight increase in PostgreSQL connections, firewall traffic, and a more noticeable increase in CPU</li>
<li>DSpace sessions are normal</li>
<li>The number of unique hosts making requests to nginx is pretty low, though it&rsquo;s only 6AM in the server&rsquo;s time</li>
</ul>
</li>
<li>I see one IP in Sweden making a lot of requests with a normal user agent: 80.248.237.167
<ul>
<li>This host is on Internet Vikings (INTERNETBOLAGET), and I see 140,000 requests from them in Solr</li>
<li>I see reports of excessive scraping on AbuseIPDB.com</li>
<li>I&rsquo;m gonna add their 80.248.224.0/20 to the bot-networks.conf in nginx</li>
<li>I will also purge all the hits from this IP in Solr statistics</li>
</ul>
</li>
</ul>
