This was the place where a single volunteer said they no longer wanted to maintain rt.cpan.org, no discussion was offered to allow someone else the opportunity to pick this up. Mails from people not in this group were ignored, as was the pleas from members (some responsible for toolchain and other core perl stuff) that this would cause chaos. This was something not widely publicised, coming as a surprise to many, others I suspect just never found out. Not until this gained a wider audience elsewhere (p5p, even though it could be considered 'off topic' for that list) was something done, almost at the last minute, to stop rt.cpan from closing.
