On February 26, 2021 at 13:00 UTC Twilio’s Outbound SMS API experienced high error rates and stopped responding to requests in a timely fashion. This action caused unscalable resource consumption on our PingID servers which in turn degraded on all authentication traffic. The SRE team worked quickly to disable traffic to Twilio, in order to mitigate the immediate issue and maintain service levels for all other PingID authentication solutions. At 15:14 UTC the Twilio’s outbound SMS API service was restored. Outbound SMS services were restored shortly thereafter.
We are working with our service partner and application teams to further improve our services.
