Hi,
I've done some looking around and don't see evidence of widespread issues with connectivity to Wikimedia from either Telekom ZA, or Africa in general.
For any users who are having troubles, please see https://wikitech-static.wikimedia.org/wiki/Reporting_a_connectivity_issue
Even if you can't follow every step there, the contents of a traceroute would be helpful.
If you're unable to reach Phabricator to file a private task, you are very welcome to email me directly!
All the best,
