McCarthy Holdings Inc.

We are providing an update on the disruption affecting the Middle East (UAE) (me-central-1) Region. After a thorough assessment, we have determined that we are unable to restore access to the resources and data hosted exclusively in the mec1-az2 Availability Zone. We continue to work on recovering regional resources, as well as zonal resources hosted in the other affected Availability Zones (mec1-az1 and mec1-az3). Since the disruption began in March, most customers have been able to re-establish their operations in other Regions by restoring backups or copying data that remained accessible. AWS Support remains available to help customers who need assistance moving their applications to alternate Regions. We remain committed to supporting our customers in the UAE. We are working on replacing the affected infrastructure and will provide an update on the restoration of our services in the coming months. We have notified the relevant authorities and continue to work with them toward that goal.

We are continuing to work with affected customers and their email providers to resolve the issue. Until then, users should check spam or junk folders and confirm that their email provider allows Docusign addresses. Envelope delivery emails are not affected.

On October 28, 2026, at 9:45 AM PT, the Engineering Team became aware of an issue with the email service that caused delayed or failed delivery of outbound SMS messages, including two-factor authentication (2FA) verification codes and SMS alerts. Initial findings indicate this is tied to a service disruption with our downstream telephony carrier, China Mobile. Users waiting on verification codes may experience delays of several minutes. If available, please opt for backup verification methods such as authenticator apps or email. We are actively working with the carrier to monitor the situation and will share our next update as soon as more information becomes available.
