There appears to be about 50ms delay between two Shaw internal nodes, and then another 50ms to a node called "equix.asbn.twtelecom.net".
What's going on?
asbn refers to Ashburn, Virginia which is 48 kilometres outside of Washington, DC. A very popular peering point as well as Chicago and New York.
It sounds like at one point you had a route going via Seattle but now it is going via Ashburn and then back across to Seattle adding the additional latency with the longer path.
