On Wednesday, Philippine airspace was temporarily closed due to a glitch in the system. Officials have cited the cause of the glitch as an outdated system, though they have not provided any further details on the specific nature of the system or the glitch itself. The closure caused delays and disruptions for travelers, and authorities are working to resolve the issue as soon as possible. It is not yet clear how long the airspace will remain closed or how the glitch will be addressed. In the meantime, authorities are urging travelers to check with their airlines for updates on the situation and to allow for extra time for their journeys.
During a press conference on Sunday, the Director General of the Civil Aviation Authority of the Philippines (CAAP), Manuel Tamayo, explained that a failure in one of the uninterruptible power supplies (UPS) caused the system to go offline. After the system was reconnected to the power supply, a warning was issued due to an over voltage issue, as 380 volts were being inputted instead of the expected 220 volts. This caused issues with the very small aperture terminal (VSAT) which also needed to be addressed. Tamayo stated that troubleshooting efforts were underway to resolve these issues.
