What time frame do you determine to be instability? The following is
from a box that has ~25 neighbours. Since the box was reloaded (6w3d
ago), I've had the same uptime with the Team Cymru neighbours as I do
with internal gear. I can't say that I've experienced any instability at
all. It is not uncommon for me to have noticed uptimes well beyond 30w.
