Update: The site is back online and seems to be fully functional.
People who are going to visit Apple's support community tonight will be told that Apple is updating the forum error message and is said to be "coming back soon." Some users can intermittently access the site.
It is unknown for Apple to take the support community offline so far. In many cases, such signage shows a big review, unlike the simple maintenance of the site, but it is unknown whether it is so.
The error is as follows.
We will be back.
We are busy updating the Apple Support Community for you and we are due to return soon.
Unlike many other Apple services, the Apple support community is not on the company's system status page, which currently does not report problems.
