I have no explanation for this. Bizarre, indeed. The first thing I try is to cycle power on all three routers simultaneously. Leave them off for at least 20 seconds. Sometimes they just lose their marbles. Failing that, mtr (package mtr-tiny for the command line version) is an excellent diagnostic tool for this sort of thing. It will tell you where a problem lies much better than ping will. E.g.: mtr -r -i 3 -c 10 debian.org -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
