This Windows 10 Setup Script turns off a bunch of unnecessary Windows 10 telemetery, bloatware, & privacy things. Not guaranteed to catch everything. Review and tweak before running. Reboot after running. Scripts for reversing are included and commented. Fork of https://github.com/Disassembler0/Win10-Initial-Setup-Script (different defaults). N.…

The problem with CloudFlare's DNS "CNAME flattening" TTL

[attaching this to a CloudFlare survey why I left them (for DNSimple)]

I was a free user using CloudFlare only for DNS, chiefly because it can simulate CNAME at an apex domain. The apex domains mathdown.net,mathdown.com point to mathdown-cben.rhcloud.com. Cloudflare "CNAME-flattening" nicely returns an A record; unfortunately it's served with a huge TTL of 7 days(!), which causes a long outage when the underlying IP changes.

I asked support how I can lower the TTL (BTW it's great that you provide free support at all) and was told [https://support.cloudflare.com/hc/en-us/requests/522551, emphasis mine]:

This is based on the TTL of your authoritative provider for mathdown-cben.rhcloud.com:
