<p class="MsoNormal">Again today, on the heels of the 2h 47m DDoS-related outage yesterday, right at<br>
11:01am US EDT (15:01:28 UTC), our monitoring alerted us to another incident at<br>
Bandwidth. The impact to us was much reduced this time, as we saw some flapping<br>
of their SIP Inbound SBCs, but around 15:20:12 UTC it was responsive enough to<br>
fall below our thresholds.<br>
<br>
The API started acting up at 14:56:00 UTC, but recovered, and then has been<br>
flapping between OK and degraded since then. As of 21:52 UTC, the API and<br>
Portal/Dashboard are either non-responsive, slow, or degraded.<br>
<br>
Inbound Voice Traffic has remaind at expected historical levels throughout.<br>
I have not checked on Termination, but it was working earlier today without<br>
issue.<br>
<br>
Latest from BW <a href="https://status.bandwidth.com/" target="_blank">https://status.bandwidth.com/</a><br>
<br>
     Update - Bandwidth teams have observed expected call behavior for 911<br>
     calls. 911 calls are processing as designed and are fully restored. Teams<br>
     continue to work on standard voice traffic.<br>
<br>
     Sep 26, 17:20 EDT<br>
<br>
I question the phrase "processing as designed" which implies it is not<br>
working as the end user expects... odd.<br>
