there is a problem on the IS KZN network causing additional latency and slow speeds when connecting over IPC (ie dsl+telkom ftth). IS did send out a notification, they are attending to it.
also keep in mind, due to the seacom outage, international traffic sourced from KZN will be rerouted out via their CTN pop.
could those in kzn do a test or two and see if there are any improvements
