Yahoo Groups Problems?????

Hi Gang,
Be aware there is something going on at Yahoo. Several lists have
been been rendered empty of all past messages and files.
I checked at the Sherline list and it has been done so. No files
and now posting is actually non functional. I do not get my own
posts via e/m.
Is anyone aware of the situation at Yahoo.com?
I hope it's just a server bug and all will return to normal soon.
There are no "News" items on the main Yashoo site page speaking
of problems.
