So we moved from 6.0 to 6.7 last year, when we refreshed the servers.
Not sure why they hid the fact that they can breach the 9,000 mark:

Yeaaaaah... RR's are critical infrastructure. I'd prefer not to mess
with them beyond what is necessary :-).

So we only worry about this on our RR's.
Other VM's that may be running are not a huge concern.
Despite our network being able to carry 9,192 bytes, we only guarantee
9,000 for services and customers, end-to-end. Same applies to internal
services we operate.
