I made two posts to this group on 30 June, around 21:00 UTC.  Both received 
acknowledgements, but neither have appeared.  A post to the users group, 
made at about the same time, appeared there immediately.

New messages later than my posting time are appearing, so it doesn't look 
like it's back-log.

Are there any known problems?

Apologies if this should be directed elsewhere, but at the moment there 
doesn't seem to be a route open to www.boost.org (to find out); certainly 
from my ISP...sigh.
