ISC has experienced a number of routing challenges at our Chennai node over the past year resulting in problems such as this one. We've been working with APNIC (the node Sponsor) and NIXI (the node host) to get these resolved. We've found the Indian market to be rather unique in the way various large ISP's chose to announce (or not announce, as the case may be) their routes at various exchanges. In this particular case it appears that the traffic is making it to our Chennai node, but not making it back.</div>
<div><br></div><div>I will work with Anurag directly in the ticket to get this issue resolved. If anyone else is seeing issues in India please mail <a href="mailto:noc@isc.org" target="_blank">noc@isc.org</a> to open a ticket. The more reports we have of problems the more attention we can get this issue with the various parties involved.</div>
