alt textMemair DNS

Pseudorandomly block social media on 50% of days. Blocking occurs at the DNS level, affecting both social media websites & their apps. Social media apps will still open, however they will not have connectivity which prevents new content, notifications, etc.

Use cases:

  • Conducting A/B tests on the effect of social media
  • Noticing the influence of social media usage
  • Reducing social media usage

Private DNS: dns.memair.com
IP DNS: 35.224.0.214

Blocked Social Media Sites

  • Facebook
  • Imgur
  • Instagram
  • LinkedIn
  • MySpace
  • Pinterest
  • Reddit
  • Tumblr
  • Twitter

Please create a pull request if you would like to block additional social media sites or domains. See the Full Block List here.

Experimenting

We're currently working on a framework to make experimenting easier. Follow us on Twitter to get updates (we will only be posting on unblocked days).

How it works

Each day at 00:00 UTC, the DNS server has a 25% chance of changing state from blocked to unblocked or vice versa. Details on how this is calculated can be seen in update.py. The status of each day in 2020 is available here.
