openDNS performing better in India now!

Hello everyone!

 

Seems like Tata Communications routing table is changed (call it fixed) to route traffic for openDNS to Singapore. It’s not going to London anymore and I see very good latency from BSNL too (which uses Tata Comm for most of it’s International traffic).

 

Here’s latest routing from BSNL to openDNS: 

 

HOST: laptop                                                                 Loss%   Snt   Last   Avg  Best  Wrst StDev
  1. router2                                                                        0.0%    50    2.0   1.7   1.5   2.2   0.2
  2. 117.207.48.1                                                             2.0%    50   25.4  26.2  24.5  36.1   1.6
  3. 218.248.173.38                                                        0.0%    50   26.1  31.2  25.0 125.5  17.8
  4. 121.244.68.114.static-lvsb.vsnl.net.in               2.0%    50   70.1  72.2  69.4  97.8   6.0
  5. 172.31.61.210                                                            0.0%    50   92.9  94.8  92.9 109.0   2.2
  6. ix-4-2.tcore1.CXR-Chennai.as6453.net            0.0%    50   94.3  98.4  93.1 154.6  12.6
  7. if-5-2.tcore1.SVW-Singapore.as6453.net          0.0%    50  127.2 130.6 125.8 165.5   8.5
  8. if-2-2.tcore2.SVW-Singapore.as6453.net         0.0%    50  126.8 128.6 124.4 178.2   8.3
  9. Vlan1807.icore1.SVQ-Singapore.as6453.net   2.0%    50  135.4 132.3 126.1 140.4   4.4
 10. 203.208.186.101                                                      0.0%    50  202.4 163.6 156.9 256.5  17.5
 11. 203.208.153.110                                                       0.0%    50  159.1 166.8 157.0 272.4  23.6
 12. 203.208.190.166                                                      2.0%    50  160.3 160.6 158.6 191.9   4.6
 13. resolver1.opendns.com                                           2.0%    50  159.0 158.3 156.9 162.4   1.0

 

Overall I am getting latency from 160ms which seems OK considering 25-30ms latency for DSL, adding 60-90ms for route till South India followed by 30-40ms latency between Chennai and Singapore and eventually destination openDNS node on ASN 36692. 

 

Oh and btw I was lucky enough to meet DNS godfather David Ulevitch at openDNS HQ in San Francisco during last US trip. A very impressive personality!

 

Well that’s all for now. Will be posting a couple more updates soon. Have a good week ahead!
