The CrowdStrike outage contributed to Jetstar’s cancellations doubling in July, rising from 153 in June to 299 last month.
New figures released by the Department of Transport’s Bureau of Infrastructure and Transport Research Economics (BITRE) also revealed, industry-wide, just 72.5 per cent of flights departed on time, compared to 77.8 per cent the prior month.
The international IT shutdown on 19 July – dubbed the world’s biggest ever – was caused by a bungled software update issued by cyber security provider CrowdStrike.
“This month’s on-time arrivals figure was lower than the long-term average performance for all routes (80.9 per cent), and the on-time departures figure was also lower than the long-term average (82.0 per cent),” said BITRE’s latest release.
“The rate of cancellations was higher than the long-term average of 2.2 per cent.
The now infamous CrowdStrike update caused blue screens of death on Microsoft’s Windows operating systems, which prevented many firms from accessing their cloud-based services.
For airlines, this particularly impacted boarding, check-in and baggage data. Jetstar was forced to cancel virtually all flights until 2am the next day after its baggage systems were affected and check-in issues occurred.
The airline also had to contend with its communication system being affected, making it difficult for the business to contact customers.
Despite the delays, most services returned to normal the next day.
