My groups.io stuff is still working - was on it all day and never closed it.
Mods and members can't get on the site. 
From one mod:
My Norton


From another:
I can’t access the group at all right now as my security software has suddenly blocked Groups i.o. as a known malicious site.


Also the member who can't access says all links to groups.io bring up warnings from Outlook about maleware (even the old digests)
