&lt;li&gt;We&amp;rsquo;ve been getting two alerts per day about CPU usage on the new server from Linode&lt;/li&gt;
&lt;li&gt;These are caused by the batch jobs for Solr etc that run in the early morning hours&lt;/li&gt;
&lt;li&gt;The Linode default is to alert at 90% CPU usage for two hours, but I see the old server was at 150%, so maybe we just need to adjust it&lt;/li&gt;
&lt;li&gt;Speaking of the old server (linode01), I think we can decommission it now&lt;/li&gt;
&lt;li&gt;I checked the S3 logs on the new server (linode18) to make sure the backups have been running and everything looks good&lt;/li&gt;
&lt;li&gt;In other news, I was looking at the Munin graphs for PostgreSQL on the new server and it looks slightly worrying:&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img src=&#34;2016/12/postgres_size_ALL-week.png&#34; alt=&#34;munin postgres stats&#34; /&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;I will have to check later why the size keeps increasing&lt;/li&gt;
&lt;/ul&gt;
