[Ntp] Announcing a new experimental Roughtime server

[Christopher Patton <[e-mail]>]

Hi NTP, this email is to announce a new Roughtime server operated by
Cloudflare:

{

   "name": "Cloudflare-Roughtime-2",

   "publicKeyType": "ed25519",

   "publicKey": "0GD7c3yP8xEc4Zl2zeuN2SlLvDVVocjsPSL8/Rl/7zg=",

   "addresses": [

     {

                    "protocol": "udp",

       "address": "roughtime.cloudflare.com:2003"

     }

   ]

}

Our server currently implements draft 08. We will soon move to draft 09
without backwards compatibility for 08, unless we see a significant number
of clients using draft 08. We will continue to support Google Roughtime,
since we do see a significant amount of traffic for that version. You can
use the public key above with either IETF or Google-Roughtime.

Note that this server is intended to support interop testing by the
community and is not guaranteed to stay up long-term.

Please report any bugs you find to our GitHub:
github.com/cloudflare/roughtime

Thanks,

Chris P. and Luke Valenta
