We've launched two Inter-Planetary Network Indexers #IPNI nodes! One node in Berlin launched in August, and one node launched in Fremont, California just last week.
These two nodes are included in the 'default' configuration of #IPFS and are transparent to users. IPNI nodes help IPFS users so they don't have to broadcast what they're looking for to the whole network as much!
