We have some proprietary software that utilizes RingCentral's FaxOut API. On March 22nd we experienced problems. Today I confirmed that our faxes are not reaching their destination. When I check the fax api, I receive a 503 Service Unavailable response.

Is there something I can do to resolve this?
