Those traces are falling apart as you cut through TATA's segments---possibly just outside of Montreal, or along the US/CA border.

Unfortunately, outside of forwarding those traces to your ISP and SE, asking them to get in touch with TATA to either fix it or alter their roting to avoid the offending segments... nope, not much you can do to resolve it. Nor SE for that matter. Your ISP is actually your best advocate in this matter.
