It was a dynamic denial of service (dDOS) attack.  Specifically, it was a new version of an NTP amplification attack.</p>
<p><strong>So, we were the only people impacted?</strong><br />
No&#8230; in fact, many sites globally were involved, see the map below.</p>

<p><strong>What destination were they trying to get into? Was there a specific destination or service they were trying to crack into?</strong><br />
For our specific situation, the attack was against our Internet connection &#8211; so they there was no attempt to break into or crack into any information system. Instead, it was simply a malicious attack that&#8217;s goal was to be annoying &#8211; and it succeeded.</p>

<p><strong>Is everything back to normal?</strong><br />
Yes, by mid spring break, the attacks had been contained and our internet access was back normal and has remained normal since.</p>
