<h1>Severity Levels</h1>
|
|
|
|
<p>The first step in any incident response process is to determine what actually constitutes an incident. We have two high level categories for classifying incidents: this is done using "SR" or "IN" defintions with an attached priority of "Minor", "Normal" or "Major". "SR" are "Service requests" initiated by a customer and usually do not constitute a critical issue (there are exceptions) while "IN" are "incidents" which are generally "urgent".</p>
|
|
<p>All of our operational issues are to be classified as either a Service Request or an Incident. Incidents have priority over Service Requests provided that there are no Service Requests with a higher priority. In general you will want to resolve a higher severity SR or IN than a lower one (a "Major" priority gets a more intensive response than a "Normal" incident for example).</p>
|
|
<div class="admonition note">
|
|
<p class="admonition-title">Always Assume The Worst</p>
|
|
<p>If you are unsure which level an incident is (e.g. not sure if IN is Major or Normal), <strong>treat it as the higher one</strong>. During an incident is not the time to discuss or litigate severities, just assume the highest and review during a post-mortem.</p>
