Any incentive to run a centrelay?

If you run your own certrelay, then your queries are private.

Operators have an incentive to keep the network operational because they sell handles. Users want their handles resolvable too. Luckily, certrelays are small and since HTTP based we can take advantage of caching, CDNs ... etc so quite cheap to run.

Also, no claim mail for me too.

sent an email. thanks
