## From the sources

This incident has been resolved. MMS delivery from Australian network subscribers to Twilio Australia Phone Numbers is operating as expected within documented specifications. Media attachments under 1MB continue to deliver normally. Attachments exceeding 1MB remain subject to carrier constraints and best-effort delivery. We recommend keeping all media payloads under 1MB to ensure consistent delivery.
