A few users noticed that CGSpace wasn&rsquo;t loading items today, item pages seem blank
I looked at the PostgreSQL locks but they don&rsquo;t seem unusual
I guess this is the same &ldquo;blank item page&rdquo; issue that we had a few times in 2019 that we never solved
I restarted Tomcat and PostgreSQL and the issue was gone
Since I was restarting Tomcat anyways I decided to redeploy the latest changes from the 5_x-prod branch and I added a note about COVID-19 items to the CGSpace frontpage at Peter&rsquo;s request

<li>I looked at the PostgreSQL locks but they don&rsquo;t seem unusual</li>
<li>I guess this is the same &ldquo;blank item page&rdquo; issue that we had a few times in 2019 that we never solved</li>

</ul>
<ul>
<li>Also, Linode is alerting that we had high outbound traffic rate early this morning around midnight AND high CPU load later in the morning</li>
<li>First looking at the traffic in the morning:</li>
</ul>
<pre><code># cat /var/log/nginx/*.log.1 /var/log/nginx/*.log | grep -E &quot;01/Jul/2020:(00|01|02|03|04)&quot; | goaccess --log-format=COMBINED -

</code></pre><ul>
<li>64.39.99.13 belongs to Qualys, but I see they are using a normal desktop user agent:</li>
</ul>
<pre><code>Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_5) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.1.1 Safari/605.1.15
</code></pre><ul>
<li>I will purge hits from that IP from Solr</li>
<li>The 199.47.87.x IPs belong to Turnitin, and apparently they are NOT marked as bots and we have 40,000 hits from them in 2020 statistics alone:</li>
</ul>
<pre><code>$ curl -s &quot;http://localhost:8081/solr/statistics/select&quot; -d &quot;q=userAgent:/Turnitin.*/&amp;rows=0&quot; | grep -oE 'numFound=&quot;[0-9]+&quot;'
numFound=&quot;41694&quot;
</code></pre><ul>
<li>They used to be &ldquo;TurnitinBot&rdquo;&hellip; hhmmmm, seems they use both: <a href="https://turnitin.com/robot/crawlerinfo.html">https://turnitin.com/robot/crawlerinfo.html</a></li>
<li>I will add Turnitin to the DSpace bot user agent list, but I see they are reqesting <code>robots.txt</code> and only requesting item pages, so that&rsquo;s impressive! I don&rsquo;t need to add them to the &ldquo;bad bot&rdquo; rate limit list in nginx</li>
<li>While looking at the logs I noticed eighty-one IPs in the range 185.152.250.x making little requests this user agent:</li>
</ul>
<pre><code>Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:76.0) Gecko/20100101 Firefox/76.0
</code></pre><ul>
<li>The IPs all belong to HostRoyale:</li>

<li>It&rsquo;s only a few hundred requests each, but I am very suspicious so I will record it here and purge their IPs from Solr</li>
<li>Then I see 185.187.30.14 and 185.187.30.13 making requests also, with several different &ldquo;normal&rdquo; user agents
<ul>
<li>They are both apparently in France, belonging to Scalair FR hosting</li>
<li>I will purge their requests from Solr too</li>
</ul>
</li>
<li>Now I see some other new bots I hadn&rsquo;t noticed before:
<ul>
<li><code>Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0) LinkCheck by Siteimprove.com</code></li>
<li><code>Consilio (WebHare Platform 4.28.2-dev); LinkChecker)</code>, which appears to be a <a href="https://www.utwente.nl/en/websites/webhare/">university CMS</a></li>
<li>I will add <code>LinkCheck</code>, <code>Consilio</code>, and <code>WebHare</code> to the list of DSpace bot agents and purge them from Solr stats</li>
<li>COUNTER-Robots list already has <code>link.?check</code> but for some reason DSpace didn&rsquo;t match that and I see hits for some of these&hellip;</li>
<li>Maybe I should add <code>[Ll]ink.?[Cc]heck.?</code> to a custom list for now?</li>
<li>For now I added <code>Turnitin</code> to the <a href="https://github.com/atmire/COUNTER-Robots/pull/34">new bots pull request on COUNTER-Robots</a></li>
</ul>
</li>
<li>I purged 20,000 hits from IPs and 45,000 hits from user agents</li>
<li>I will revert the default &ldquo;example&rdquo; agents file back to the upstream master branch of COUNTER-Robots, and then add all my custom ones that are pending in pull requests they haven&rsquo;t merged yet:</li>
