Apple partially restored its main website for developers, eight days after shuttering it in response to a cyber attack. The web site was back online on Friday, though some sections, including the forums and the member center, were still offline.

"Certificates, Identifiers & Profiles, software downloads, and other developer services are now available," Apple said in a developer update page on the site.

Seven of the 15 services on the website, including the iOS, Mac and Safari developer centers, were online at 8:15 p.m. ET on Friday.

iOS developers use the site for software downloads, documentation and engineering information.

Apple apologized for "significant inconvenience" that the outage caused for software developers.
