October 21st – Partial service outage

4.52 AM UTC. We’re currently experiencing a partial service outage due to issues with our API.  As a result, it is currently not possible to sign up for new accounts or sign-in to existing accounts. The phone number and outbound call pricelist on our website will also not work in addition to our free business messenger.

However, this does not affect our telephony services – incoming and outgoing calls should continue to work as expected.

The issue is being investigated with high priority. We sincerely apologize for the inconvenience.

5.31 AM UTC. The service has been partially restored. However, we still see issues with some of our APIs due to which sign-up for new account and sign-in to existing accounts may still not work. The root cause of the issue has been identified and we are taking actions to resolve it.

6.30 AM UTC.  All our services are now back online.

The root cause of the issue was found to be an attack on our service to create several junk accounts. Our investigation has found that the attack used a botnet in an attempt to overwhelm our existing security functions. The attack was limited to creating new accounts. We have taken additional steps to mitigate the attack.
