SEATTLE—A pre-dawn outage at Amazon Web Services on Monday rippled through many credit unions nationwide, knocking out or slowing online banking, mobile apps, call centers, authentication and bill pay at institutions from Navy Federal to community CUs in Iowa, Wyoming, Arizona and California.
While Amazon traced the disruption to DNS issues in its U.S.s-East-1 Region, recovery was uneven for much of the day—illustrating how much CU digital infrastructure depends on a few cloud providers.
By late Monday, according to news reports, many services had stabilized, but not before members encountered failed logins, slow or unavailable apps, and jammed phone lines.
Several CUs posted AWS-specific service alerts—including Department of Commerce FCU, WyHy FCU, Spectra CU, Robins Financial CU, Andrews Federal CU, Coast Central CU, First American CU, Greater Iowa CU, Oregonians CU, and evolve FCU.
Navy Federal, according to news reports, confirmed some platforms were disrupted. Vendors in the payments stack such as Plaid also reported AWS-related degradation, compounding access and verification hiccups.
