There were 117 NMI outages since March 2023. The 47 outages from the last 12 months are summarized below, with incident details, duration, and resolution information.
NMI experienced degraded transaction processing for 1.4 hours, specifically affecting the Transaction API and TSYS processor, causing transaction processing failures and funding delays. The issue was identified as impacting only TSYS transactions, with merchants scheduled for the 2:30 AM ET settlement job experiencing delayed settlement at an alternate time. Engineers implemented a fix and confirmed all services returned to normal operation.
The Worldpay eCommerce (formerly Litle) platform experienced delayed settlements for 50 minutes while engineers investigated the issue. The incident affected the Worldpay/Vantiv components and was resolved when all outstanding settlement batches received responses.
NMI experienced elevated email delivery failures to Microsoft consumer domains (outlook.com, hotmail.com, msn.com) due to Microsoft-side filtering controls, affecting password reset emails, OTP codes, device codes, settlement reports, and transaction receipts. Microsoft 365 accounts remained unaffected, and users were advised to use alternate email providers as a workaround. Microsoft implemented mitigation after 6 days and fully resolved the issue after 164 hours total duration.
