BSNL-Softlayer issue

Seems like BSNL-NIB (AS9829) routing with Softlayer’s Singapore datacenter (AS36351) is messed up.

Example route between BSNL consumer connection (from Haryana, India) to Softlayer hosted site dot19.com

Messed up routing tables of BSNL or lack of co-ordination between Tata Comm & Softlayer?

  1. Earlier in the day, TATA reported issues on their network. Our NOC rerouted traffic to avoid customer impact, and as the stability of the network is verified, the routes will be restored.
