data.worldbank.org does not respond to ICMP packets which makes it look like loss in a MTR.
We use Openserve transit for international. We do not route traffic to Telkom's network instead buy international transit capacity from Openserve. Openserve is a transit provider just like Seacom, WIOCC, HE and others.
***Due to ongoing authentication issues on Openserve we have removed the CLID locks on accounts so authentication will go through however the speeds are capped at 1Mbps when this occurs. Clients on ADSL and Openserve fibre are affected nation wide. We are working with Openserve to find a solution soon. Apologies for this.
