<h1>DTI is down for the count?!</h1>
<p>
Hrm, it looks like the DTI application has crashed all the
way into the ground?? 😬
</p>
<p>
This can happen when our system gets overloaded, or when the
team is working on something and we hit the wrong button 😓
</p>
<p>
We'll be notified of this outage, and we'll do our best to
be back up soon! 💖
