At ADAvault we use Cloudflare for DDoS protection and CDN caching. An interesting byproduct of this that we get data for use of the Daedalus wallet access on a per country basis. This is because the wallet checks the json files on our site for data on the ADV stake pool, and therefore this gives us a proxy measure for adoption of cardano globally.
Adoption rates are highest in the US, Canada, UK, Germany, Japan, Australia and South Korea. Overall there is a pretty impressive coverage globally, but still some room for progress in Africa where the Cardano Foundation have plans to boost adoption.
This ability will stop with the rollout of SMASH in Daedalus 2.3.0 as all data will be routed centrally via IOHK or community servers:
With this Daedalus update, stake pool off-chain data (name, ticker symbol, homepage, and description) is obtained from the IOHK stake pool metadata aggregation server (SMASH). Previously, Daedalus obtained off-chain stake pool data individually from each stake pool, which was time consuming and error-prone. In a future upgrade, Daedalus wallet users will be able to choose an alternative server in the configuration and access any community server of their choice.

It’s a sensible change, the current structure allows for a number of potential privacy and security attacks.
