    Comerica Bank is temporarily suspending participation on the RTP (Instant Payments) network while it converts to Fifth Third Bank, from Thursday, September 3, 2026 at 9:00 PM ET through Tuesday, September 8, 2026 at 3:00 AM ET. During this window, any RTP payment sent to the following Comerica routing numbers will be rejected: 121137522, 111000753, 067012099, 072000096. This affects the receiving/counterparty side only; no Modern Treasury Internal Accounts are impacted. We recommend completing any time-sensitive RTP payments to these accounts before the window begins, or holding until normal processing resumes after September 8. No action is required once the window closes; processing will resume automatically..

Archive proof

Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves this record existed by then and has not been changed since, by anyone, Rewindex included.

How the archive is checked, and what it cannot prove.

Rewindex captured a newer version after the last checkpoint; the next run () commits it.

Impact, status and times are the vendor’s own, as last archived. View on status.moderntreasury.com (opens in new tab).
