A Wednesday-night computer outage at SFO's international terminal knocked out ticket-counter systems and forced manual check-ins — one day after a separate FAA ground stop, and against a backdrop of billions committed to fixing the airport's fragmented IT infrastructure.

Computer systems at San Francisco International Airport's international terminal went down Wednesday night, July 8, knocking out ticket-counter terminals and forcing airline staff to revert to manual check-ins. Up to 14 departing flights were delayed between five minutes and an hour, according to NBC Bay Area, which reported on-record remarks from the airport's duty manager.

"The issues impacted some ticket counters, meaning that some of the computers were not being used in the terminal," the duty manager told NBC Bay Area. "A team is looking into the computer issues." The root cause has not been publicly disclosed.

The failure arrived one day after a separate, unrelated FAA-issued ground stop at SFO — active from 9:53 p.m. to 11:15 p.m. PDT on July 7, due to Western U.S. air traffic control center operations, per Reuters. The two events were independent; no FAA action was in effect during or because of the Wednesday computer failure. SFO is also operating under reduced runway capacity through October 2026, with Runway 1 Right closed for construction, cutting arrival throughput from 54 to 36 aircraft per hour.

The vendor picture adds context the airport hasn't provided. SFO approved a contract extension in May 2026 with SITA Information Networking Computing USA Inc., valued at $16,780,546, for shared-use passenger processing system support — the centralized infrastructure that ticket-counter terminals depend on, per SFO Commission records. SFO has not confirmed whether SITA's systems were involved in Wednesday's outage; the contract extension at least confirms SITA remains the airport's operating partner for that infrastructure layer. The September 2024 cyberattack on Collins Aerospace's MUSE check-in platform — which cascaded into manual processing at Brussels, Heathrow, and other major airports — is the recent precedent for how shared passenger-processing software becomes a single point of failure across institutions.

The outage arrives as SFO's own leadership has publicly diagnosed exactly this kind of fragility. Iyad Hindiyeh, the airport's Chief Digital Transformation Officer, stated that "we want to ensure that technology is not purchased in silos, because data stays in its silo and then after a while it becomes a technical debt." That assessment was offered to justify SFO's Technology Improvement Program, launched in 2025.

Capital commitments behind the improvement push are substantial: the airport's current Capital Improvement Plan allocates $8.0 billion under the Ascent Program – Phase 1.5, including a new Airport Integrated Operations Center targeted for completion in early 2026, per city planning documents. Whether that center was operational enough Wednesday night to contain or shorten the outage is one of several questions SFO has not answered.

What remains unconfirmed: the root cause of the July 8 failure, which specific systems or vendors were involved, how many passengers beyond the 14 affected departures were disrupted, and whether the airport will release a formal incident report.
