Howdy.

At home, I have Eastlink.  At work, Aliant.  I've been
comparing mtr reports to various destinations and I see
significant packet loss along Aliant hops which do
not show up in Eastlink hops.

e.g. www.cnn.com on Aliant:

It isn't specific to CNN.

Can anyone else on Aliant confirm if there are problems
in recent days like this, or is this experience unique from
our location?
