Nexmo messages not delivered

On October 17, one of Nexmo's US partners identified un-permitted content in outgoing SMS and advised Nexmo to stop that traffic immediately. As a result, Nexmo temporarily blocked all messages sent from that route, which included all messages sent by users with virtual numbers in the US and Canada under Telerivet's Nexmo account. Nexmo has not indicated whether any Telerivet user was responsible for sending un-permitted content.

Nexmo has reported that they are planning to improve their internal processes to avoid a situation like this from happening again.

Telerivet has already been updated to require manual approval of each user who requests to send messages via Telerivet's Nexmo account, to reduce the risk of Telerivet users sending un-permitted content.

Telerivet has already credited affected users with the cost of messages that were not delivered due to this issue, as well as 25% of their monthly service plan fee.

SMS messages sent via Nexmo are being delivered again now. The issue was limited to clients using Telerivet's Nexmo account to send SMS messages in the United States and Canada. Clients using their own Nexmo account were unaffected. Nexmo disabled Telerivet's SMS routes in the US and Canada at 7:25 AM PDT, without notifying Telerivet. Nexmo restored these routes at 2:43 PM PDT. Telerivet is continuing to communicate with Nexmo to determine the reason why Nexmo disabled Telerivet's SMS routes in the US and Canada, and to prevent this issue from reoccurring.

Users with routes provided by Nexmo have been reporting that messages are currently not being delivered with the error "Unroutable". Telerivet is currently working with Nexmo to resolve this issue.
