Apple discussion forums unavailable?

Solution 1:

No issues here.
Nothing on Apple's status report - https://www.apple.com/uk/support/systemstatus/
A quick Google search seems to find only that one site, iphonetricks, reporting it as an issue.

If you need to check a site is down, try https://downforeveryoneorjustme.com

Bizarrely, they seem to think it's down, yet I can get straight in. Last post about 2 minutes ago & changing with each refresh.

In this kind of situation, I'd suspect it's not the site itself, it's the distribution network having issues in certain locations.

edit
OK, the developer community seems to have been the victim of a spam-fest. You'd think someone would be awake overnight to clean it up… but no doubt it will get tidied as soon as whoever is on call gets the call.
I've let support know. I think I fried someone's brain, their "reading from a cheat card of standard responses" was sorely tested.

Update
24 hours later they still haven't cleaned it up.
