AC/DC may be on the verge of retirement, if Tuesday's Internet buzz is to be believed.

And, as you know, the Internet is the wise, sole provider of all inscrutable knowledge.

The rumors come just weeks after frontman Brian Johnson said the band has kept a low profile in recent months due to a member's health problems. According to WENN, Johnson told Florida radio station 98.7 The Gater in February, "One of our boys was pretty ill, so we didn't like to say anything, and we're very private about things like this, so we didn't wanna say anything. And he's a very proud man."

Various reports say that member was cofounding guitarist Malcolm Young, who is rumored to be recovering from a stroke and may no longer be able to play.

However, Johnson also said the band wanted to get back to work, hinting at a 40th anniversary tour and a new album.

"I think we'll be going into the studio in May ... It's been 40 years of the band's existence, so I think we're gonna try to do 40 gigs, 40 shows, to thank the fans for their undying loyalty."

No one from the band has publicly commented on the reports.

Insiders told Billboard the rumor came from an email sent to Perth radio station 6PR from an anonymous tipster using the handle Thunderstruck. The station repeated it and -- Hello Internet! -- suddenly everyone is posting long-winded tributes on their Facebook pages. (OK, I admit, I posted something too).

Johnson sparked retirement rumors in 2011 with a remark he later said was taken out of context. He told Billboard at the time, "A journalist asked me once, 'What do you think about retirement, Brian, seeing as you're getting older?' I said something honest and quite naive; I said, 'Well, I'll retire when I can't do it anymore and as soon as I feel I can't do it anymore, then I'll retire.' Next thing I now there's a headline, 'Brian Johnson's gonna retire' and I'm like, 'Y'know, what a piece of (expletive) that guy is.' And it came out all wrong so you got to be careful what you say."
