Irony alert: Major airport to be interrupted for two hours to replace UPS Three power outages have hit NAIA in the past year. What was that about ramping up tourism? The replacement of an uninterruptible power supply (UPS) at the air traffic management center in a major airport in the Philippines will result in the entire country's airspace being shut down for two hours on May 17. The corrective action at Ninoy Aquino International Airport was originally scheduled to suspend operations for six hours on May 17. This was later shortened to between 2AM and 4AM (1800 to 2000 UTC). "After careful study, simulation, consultation with CAAP's technical team and service provider, it was agreed that the maintenance activity can be expedited by providing additional manpower and a standby UPS," CAAP spokesperson Eric Apolonio told the Philippine News Agency. ....The maintenance work follows two recent major power outages at NAIA that resulted in chaos and stranded travelers on heavy travel days – New Year's Day and Labor day weekend. The New Year's Day incident lasted for eight hours. Over 65,000 would-be passengers across 360-plus flights were stranded when the blowers in the Communications, Navigation, and Surveillance/Air Traffic Management (CNS/ATM) systems' electrical network "conked out" and the two uninterruptible power supplies failed. They had one job. It's right there in the name. Technicians at the time further complicated matters when they fried the terminals that receive satellite data from airplanes and air traffic management systems by shooting the wrong voltage into the system to bypass a damaged UPS. --- Bob Bridges, robhbrid...@gmail.com, cell 336 382-7313 /* If you don't risk anything, you risk even more. -from _How to Save Your Own Life_ by Erica Jong */ -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Mike Schwab Sent: Wednesday, May 10, 2023 01:44 https://www.theregister.com/2023/05/10/google_cloud_paris_outage_persists/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
