We had a TV in the office then, but now we don't.  The other big news
event of the week, the tornadoes in the south (especially here in
Alabama), meant we were filling up our office bandwidth much of the day
Wednesday, watching the local weathermen to find out if we (or our
family and friends) were next.  This was an exceedingly unusual event in
terms of magnitude, but the watching to see where the tornadoes go part
is fairly regular around here this time of year.  Every time there is a
severe weather outbreak, we see our bandwidth usage go up significantly
(especially when it is during the business day).

As an admin at a small ISP, I'll admit we don't have multicast set up in
our network, in part because every time I've looked, I just end up
confused.  Kind of like IPv6 was for a long time, except IPv6 has more
attention and so more people writing better (easier to understand) info.

Of course, we provide DSL via PPPoE (wholesaler, so we don't have a
choice in the setup), so there isn't much we can do to help with that
level.  That's where we could gain the most of course; we sometimes see
nearly double the DSL traffic for big events (not for the wedding
though, since most of our customers don't have electricity).  The "last
mile" is usually the bottleneck, but that's the hardest nut to crack.

I don't speak for anybody but myself - that's enough trouble.
