Australians trying to do their banking, book flights and access postal services have been locked out after a major outage affecting some of the nation's biggest companies.
Websites and phone apps went down on Thursday affecting banks, big and small, Australia Post, Virgin Australia and others.
Many services were running again after an hour or so, but affected companies say they're working overtime to make sure the problem doesn't recur.
Banking services were severely disrupted with Westpac, the Commonwealth, ANZ and St George all down, along with the website of the Reserve Bank of Australia. Services have mostly been restored.
Virgin Australia said flights were largely operating as scheduled after restoring access to its website and guest contact centre.
"Virgin Australia was one of many organisations to experience an outage with the Akamai content delivery system today," it said.
"We are working with them to ensure that necessary measures are taken to prevent these outages from reoccurring."
Akamai counts some of the world's biggest companies as customers. AAP has sought comment from the company.
Australia Post was also affected, saying an "external outage" affecting a number of its services.
Downdetector, which tracks outage information in real time, at one point listed almost 50 Australian entities experiencing problems.
