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.
Mine are not so good:

I see you have 68.22.187.24 in your list too, but my uptime is less. Are you using increased hold times?
No... I haven't changed anything.
