During this approximately 1 hour long test, we will simulate a failure of the power provider, initially forcing all equipment onto UPS support and subsequently causing our generator backup to start. We will run in this failed state for approximately 30 minutes, and then return to using normal upstream power. <br></span> </span></div><div></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>It is not expected that this test will impact service, however testing always has the potential to find faults, which could lead to downtime. </div><div><br><span class="Apple-tab-span" style="white-space: pre; "> </span>Please contact ISC with any questions or concerns at +1 (650) 423-1310 or at <a href="mailto:noc@isc.org">noc@isc.org</a>.<br><br><span class="Apple-tab-span" style="white-space: pre; "> </span>- Jim Martin, ISC Director of Operations<br></div></div></body></html>
