Carriers around the world began experiencing capacity issues a few weeks ago because of increased demand on their networks due to COVID-19. This resulted in some cases with an increase in voice quality issues, busy signals, or other errors on your phone calls. Over the last few weeks Twilio has worked directly with different carriers to detect and resolve these congestion issues as they occur.  Local network operators have been working to augment their networks and address capacity constraints. Twilio and its partners will continue to monitor the health of the global carrier networks to keep you informed with the latest status. 

If you or your customers experience any congestion related issues please report the incidents immediately to the Twilio support team.
