yes overload demand 500Mbps RM90 oversales
QuantumEdge problem is specific to ControlD and not really have anything to do with 500Mbps, much less to do with 500Mbps at RM90.
His problem is using IPv6, TM will route him to Japan consistently while using IPv4, he get routed to Singapore.
You can confirm this with traceroute -6 and traceroute -4 to force IPv6 / IPv4.
Many server will reply with regional based IP, even though they are CDN which has anycast address range. In his case, Google will reply with a Japan youtube CDN address. Unless he watch Japanese content, those are most likely not cached and youtube is known to sucks when streaming uncached content.
So he suddenly face many issue all due to using one DNS server:
1. Far away DNS server lead to high latency in resolving IP address
2. Get an IP address from far away server that introduces the Bandwidth-Delay-Product (BDP) problem
3. Gets hit with uncached content problem due to the region predominantly consuming Japanese content.
So is this really TM problem? Yes it is.
ControlD outsource all their network to transit provider. In Singapore, it is served by AS36236 NetActuate and they peer in Equinix SG.
So using Equinix Looking Glass:

You can clearly see that they advertise both IPv4 and IPv6 correctly. But what about their peering policy?
Looking at PeeringDB:
https://www.peeringdb.com/net/4549You can see that in Equinix SG, they peer with Route Server. TM also peer with Route Server for one of their Equinix SG link.
With this, we can confidently say that TM's BGP Optimization software steer ControlD IPv6 traffic deliberately to Japan.
However, I did not discount your saying that more people signing up for 500Mbps at RM90 affect speed. That one is at OLT port level due to TM's specific method to offer Unifi Ultra without investing in a single cent.
I think I just explain that in a follow up post.
But this specific problem ain't due to it.
