How would they be faster than microwave / laser terrestial towers, that already travel around the great arc?

Probably not too useful for high speed traders as they can afford and are technically sophisticated enough to relocate their systems closer to the exchange, but I know that enterprise software that suffers heavily due to latency in APAC regions. Lower-latency connectivity from those regions to EU/US datacenters will be a small game-changer for many businesses.

would that help them though? i mean it appears to me they are already as close as possible to avoid latency and use microwave links and stuff so that is pretty hard to beat i guess. the only thing i can easily imagine being beneficial is getting information across the globe faster but then i lack the skills to see how one profits from that, ie. being closer would still be better, no?
