Amazon Web Services had database issues in the Sydney area, which affected large customers like MYOB.
The cloud provider said in a Status Advisory that the Relational Database Service (RDS) hosted in Sydney was suffering from "increased build times and unavailable clusters".
The problems started at 7:42 am (Sydney time) and were finally resolved at 1:00 pm. However, the AWS said it had seen "recovery for some clusters" at 11.30.
AWS issues in the officially designated AP-SOUTHEAST 2 region were not limited to RDS only.
AWS has officially confirmed that there were issues with bugs in the Elastic Beanstalk APIs, but this has now been resolved.
The company affected by RDS outages was the accounting software vendor MYOB, which reported that 40 of its services were inactive and only two were operational.
"Our service provider AWS is currently experiencing a database outage," the company said in an advisory.
"Most customers will not be able to access their sites until the problem with AWS has been resolved."
MYOB said in an update that 211 of its own customers were affected by the RDS issues. It had some negative effects for some time, but said it was fixed at 13.32.
