Summary AI Generated
Mimecast experienced SMS delivery failures affecting all customers with Canadian phone numbers across all grids, not just the Canadian grid as initially identified. The issue prevented SMS verification codes from being delivered to Canadian phone numbers for 122.7 hours. Mimecast applied a fix and worked with their SMS provider to restore full delivery service.
We believe we have identified the issue affecting customers hosted on our CA grid who may be experiencing degraded SMS delivery performance. We are working to resolve this as a priority and will provide further updates as they become available.
