After a, Apple has revealed the cause of the extended downtime of its developer website.
"Last Thursday, an intruder attempted to secure personal information of our registered developers from our developer website," Apple said in an email sent to developers.
While Apple claimed that the site's information was encrypted, and thus unable to be accessed, the company could not rule out that developer names, mailing addresses, or email addresses were not accessed during the incident.
Apple took the site down on Thursday (US Pacific Time), and has been working to restore the site since.
"In the spirit of transparency, we want to inform you of the issue," said the company.
"In order to prevent a security threat like this from happening again, we're completely overhauling our developer systems, updating our server software, and rebuilding our entire database."
Apple apologised for the "significant inconvenience that our downtime has caused", but did not reveal a timeline for the rebuilt site to appear.
