Yes I am a lurker. 

Within the developed world, (US, Canada, Europe, Japan, Korea) losses today are usually << 1% on the networks connecting academic and research institutions. However, there are considerables losses seen to and within developing regions.  See for example slides 5, 8, 9, 10, 11, 12, 13 of http://www.slac.stanford.edu/grp/scs/net/talk05/i2-members-may05.ppt. For more details see the Jan 2005 Report of the ICFA/SCIC Monitoring Working Group at http://www.slac.stanford.edu/xorg/icfa/icfa-net-paper-jan05/

Note this data only refers to losses using ping, it does not address whether the packets are lost to congestion or BER or whatever.

Detlef, on the questions relating to Internet loss, you should talk to the folks at SLAC, who've been doing Ping-around-the-world for years.  Try Les Cottrell, who may be listening.  It was, not long ago, that peering points, especially back East, were losing 30% of frames for busy periods.  Don't know what that is today.
