One thing not covered in the discussion was geographic and hardware diversity for scraper nodes. Im sure you realise why having all scapers on AWS in the USA (for example) would be a bad idea; if AWS or the USA was offline for some time then no superblocks would occur. Clearly this isnt as serious as blockchain fullnode diversity, but 5 scrapers feels a little on the light side to me.

I can answer this for our current status. As of right now, all 5 scrapers are in unique locations and spread around the globe. At present we have scrapers covering US East, US West, the UK, Germany, and Australia. We also have a diverse group of service platforms hosting the scrapers, with at least 3 unique providers being utilized (to my knowledge). I agree more scrapers would be beneficial. Are there any other geographic zones we need to cover? Ideally we should cover more of Asia, but most node graphs seem to show a low percentage of our userbase in Asia (perhaps VPNs are masking this?).
