Hi Benoit,

just my 5 cents ...

It's not the customer's responsibility to cover issues of their TSP using an 
unreliable source of geoIP information.
The TSP would be able to whitelist exceptions to cover the gap between their 
unreliable data source and reality until their geoIP source has corrected their 
If it's a business customer, they will have a SLA with the TSP and since it's 
the fault of the TSP there is no question who is violating SLAs.

I'm pretty sure RIR's would allow MaxMind to query the original source of data, 
either for the IP or for the AS announcing the prefix to bgp.
But RIR's will charge a service fee for that - what is legit from my 
perspective. If MaxMind spares this fee and delivers a shitty service then, the 
TSP should consider to switch to a more reliable source of data - it's them who 
is violating SLAs with their customers.
