ipad-target.py VS edgedns

Way back when the Nintendo Wii was brand new and hard to find, I wrote a script to scrape Target.com for store inventory and notify me if a nearby store restocked. A few years after that I revamped it to check on inventory for newly released iPad models. I put the code up on GitHub [1] and the CTO for a company that had large-scale store inventory checking as part of their product emailed me out of the blue after seeing my repository. A little while later, I replied back, interviewed and got a pretty good job offer out of it. I wound up not taking the offer, but in hindsight I probably should have.

For the biggest pioneers, there is also a variant to build your own GeoDNS service with your own name servers. But for this to make sense and real value, anycast IP addresses would be needed. Also a number of other reliable servers around the world with DDoS protection and then understand, select and adapt eg EdgeDNS or Czech Knot DNS (which also uses Cloudflare). However, commercial GeoDNS services are relatively cheap and reliable, so we can’t imagine an ROI that would make sense with our own small, non-commercial DNS solution.
