Yahoo suffered a brief outage across most of its portals on Friday, with users reporting that virtually all links except its home page had gone dark.
The exact nature of the issue was unclear, but the loss of connectivity raised the possibility that the Internet giant may have fallen prey to a hacking attempt. In recent days, the websites and social networking feeds of several major companies have been suffered a rash of inexplicable attacks.

Yahoo issued a statement acknowledging that some of its sites were "inaccessible for a short period of time" but a source at Yahoo said it was not a hacking attack.
The company added: "We have corrected the issue and all functionality has been restored. We apologize for the inconvenience this may have caused."
However unwelcome, the outage provided a brief change of conversation from a controversy that has engulfed Yahoo for the last week. CEO Marissa Mayer recently ordered most of Yahoo's telecommuting staff back to the office, a shift in policy that proved a wide-ranging debate about working remotely.
