Not that strange
The moonfruit-mercury link is the issue.
The link should be disabled and stay disabled until upgraded.
This link could be removed from the network.
Find a new home for this link if the Moonfruit link to Mercury is being removed.
When the link is working it syncs at 45/45mbs which for a dualpole link is very bad and the performance is below old ospf standards.
The Ariel link to Mercury is not running at the moment as the Ariel side still needs to be upgraded. The upgrade is to rockect xprisms with 45degree slant dishes I can't wait to see how they perform.
Still needs to decide where their link must be pointed or just find a new home for this dish that is doing nothing for more than two years now.
