It looks like the Oracle Cloud data center in South Africa routes via the UK to the Oracle Cloud data center in Singapore.
However, the Oracle Cloud data center in South Africa routes directly to the DigitalOcean and Vultr data centers in Singapore via the SAFE undersea cable, with drastically reduced latency.
Since traffic is already being routed optimally to other data centers in Singapore, why is Oracle Cloud not doing the same to its own data center?
