@ Randy,
my head has been going round in circles and forgive my ignorance but am not sure I understand your statements above. 

i thought BGP by design presumes certain levels of high-availability (i.e. multiple redundant paths to facilitate AS_NO connectivity). Why cant the Border Routers on TEAMs and SEACOM gateways be configured to interconnect and automatically act as backup to each other - without compromising BGP convergence?

Thats why i thought it a commercial rather technical challenge.

walu.

s/if/when/

The Internet is, among other things, about building a reliable network
out of unreliable components.

All devices break. some days, multiple devices will fail at the same
time.

If you require any device to have 'high availability' you have a bad
design.

BGP never converges.
