The ping output from the Mauritius Telecom network to 196.192.112.2
(in Mauritius) is as follows:

The traffic goes from telecomplus.net to London and back to emtel.com
through another network provider. Here is the ping output from the
Mauritius Telecom network to 41.76.47.65:

The traffic goes from telecomplus.net to emtel.com. The reply at
https://twitter.com/OrangeMauritius/status/659622196529221632 is correct.

The following is part of a reply from Daniel Shaw (MIXP):

   "What I can confirm for certain is: Both Emtel and Mauritius Telecom are
    active at the MIXP.

    That is:
    - They both have an active port that is up.
    - Both their ports do show traffic.
    So we can know that they both do peer with at least one other network that
    is at the IX, possibly more than one."

Either some details were omitted from the above or the person was not
aware of the network issue.
