We have asked INSINC to take the Montreal-Halifax circuit for testing from 9:00 to 12:00 Atlantic time (1300 to 1600 UTC) on Sunday, this to take advantage of down time scheduled for half the customers affected by this outage (at NSTN). The circuit is intermittently dropping packets to CRC errors. The loss rate is likely low enough not to affect TCP, but it does make our internal routing churn from time to time and the trouble seems to be getting progressively worse. Previous tests by the telephone company have come up clean, so they claim. This is hardly surprising (past experience has shown that the tests the telephone company run have only about a 25% chance of detecting anything short of a total failure of the circuit) and it is expected that it will require some shouting to get them to actually fix this.
