UDP packets loss at Israeli ISPs during peak hours

[Etzion Bar-Noy]

It's probably due to their over commit, and it means your UDP packets are in
queue until expired.
Since Israeli ISPs has learned the trick, I tend to believe ICMP packets
have high priority, so that no customer will be able to complain. When you
can't complain, well, it means that the problem is with you.
