Hi,
I measured the adoption of RPKI ROAs that help with routing security and some other properties for the >3k BGP prefixes that make up the Tor network.

You might want to jup directly to section "Recommendations for Tor Relay Operators". (I could paste it here but then all the URLs would be lost)
Since OVH SAS and DO do not deploy ROAs at all yet:
If you are an OVH SAS or Digital Ocean customer (directly or indirectly just on the same AS) it would be great if you could ask your customer support when they are planing to deploy RPKI ROAs (like other big hosters already did).
thanks, nusenu
