While working to improve our Asia/Pac/Oceania data center, we have routed mail through alternative data centers for our customers in this region. This may cause minimal connection latency for those customers.

Today at 2:30pm MDT we attempted to optimize mail sending for these users. This caused intermittent connection timeouts for some customers connecting to that data center. As of 9:05pm MDT we reverted the changes and confirmed there are no new connection timeouts.

We apologize for any inconvenience this has caused you. Please contact our Support team with any questions: https://support.sendgrid.com.
