Sean Donelan Opined Thusly,
"Generally I don't believe ISPs that claim 100% uptime or 0% packet loss."
I have seen a "perfect score" on a Keynote evaluation, while we had a rather nasty outage outside a preststed maintenance window. When we objected that the outages was a planned maintenance that somehow escaped publication, it was ignored by Keynote - how generous! I doubt anyone here would deny the difficulty of maintaining a five 9's record, going above and beyond to claim no packet loss just tells you who they really are...
