Vodacom connections breaking Mint updates

Vodacom is tampering with packets meaning that users of Linux Mint are not able to update their systems on a Vodacom connection. This has previously been complained about on HelloPeter without resolution.

The URL is http://packages.linuxmint.com/dists/tara/InRelease, and instead of allowing access, Vodacom redirects to the appalling http://flex.vodacom.co.za/err/zerod-web/p/zerod-home/#/splash404 page.

The errors is reproducible on two different systems. I can access these packages on other connections or via a VPN. Vodacom network engineers, please correct the packet rewriting code that is breaking Mint updates.
