Between Mumbai (India) and Marseille (France), you have SMW4, TGN-EA,
SEACOM, etc... => about 100ms.
Note: Marseille is at about 21ms of London via Paris.

So far, from UK/France, with cables I've seen in use, you go East via
India to reach: Singapore, Hong-Kong.
But then, to reach Japan, you go West, via North America.
