I recently had an email support thread with @eli(unless there’s a different one) about this.
Same situation as there is roughly 100 GB of traffic split between US / India. However, most of the IN traffic gets re-routed to FRA. It appears to me that the traffic gets split between FRA / SIN at peak hours for IN. The BOM edge is completely unused.
Last April, This is only possible on fly... I posted this image and MAA was working. Later, the MAA instance was moved to SIN as it was actually faster and served Asia better.

Email response to me:
The crux of the matter is: intermediate ISPs often don't support
anycast traffic well, so in this case, routing config changes won't
resolve the issue. Instead, we need to turn up more sites nearby to
announce from — without this in place, we would see significant
disruption to our global traffic pattern.
Since this involves new hardware, it's more time-consuming than
tweaking bgp settings, but it is something that we are working to do
as quickly as we can— this is a top priority for us.
There is no clear timetable / fix for this atm as hardware will need to be deployed. It looks like they decommissioned the MAA site. I’m really hoping they get it working…and keep it working this time.
