Once upon a time, Patrick W. Gilmore via Outages <<a href="mailto:outages@outages.org">outages@outages.org</a>> said:<br>
<br>
<o:p></o:p></p>
<p class="MsoNormal">> However, Dyn is far, far better positioned to withstand attacks than a company like PagerDuty could possibly be on their own. So I think PagerDuty did the right thing in using Dyn.<o:p></o:p></p>
<p class="MsoNormal">The flip side is that the concentration of services in "specialist"<br>
hands makes it easier to attack a large number of companies at once. If<br>
PagerDuty ran their own DNS, they are not a likely target of an attack,<br>
so would be unaffected.<o:p></o:p></p>
<p class="MsoNormal"><br>
<br>
PagerDuty should, at minimum, run their own DNS in addition to using someone like Dyn. Not put all their DNS eggs in a single basket.<br>
<br>
Maybe Dyn needs to deploy anycast nodes at every internet exchange of every size and scale instead of relying on a small number of beefy anycast nodes in select locations if their customers are going to have a single point of failure.<br>
