Resolved on August 27, 2026.
Between 2026-08-27T00:30:35Z and 2026-08-27T00:48:01Z, all Visa authorizations failed with status code 40400, "backend problem". A few Visa transactions were failing already starting 2026-08-27T00:25:25Z. Mastercard authorizations along with all captures, refunds, voids and credits were unaffected. We have seen no further connectivity errors since 2026-08-27T00:48:01Z. Failed authorizations were not charged and can be retried. We are working with our upstream provider to determine the root cause and to prevent similar issues in the future.
