Up-to-date list of Roughtime servers?

[April]

Hi, is anyone aware of a list of Roughtime servers other than Cloudflare's? ( https://github.com/cloudflare/roughtime/blob/master/ecosystem.json )

It's the only one I could find.

Thanks,

April

Hi April,

I have a list of some servers that are currently running different versions of the Roughtime protocol. The draft version indicated below is the one I estimate they are implementing (or attempting to implement):

roughtime.int08h.com: iBVjxg/1j7y1+kQUTBYdTabxCppesU/07D4PMDJk2WA= : ~draft-14
ilimit-rt02.ilimit.cat: XTNZR7TIw4iMV2mNOVNPYzmWxXxg1DA16o2SYLp1k8k= : ~draft-14
ilimit-rt01.ilimit.cat: Oj8AxjzCYMlBicllTdeiJOEluLHdxijGd6sSaS993eo= : ~draft-14
sth2.roughtime.netnod.se: T/xxX4ERUBAOpt64Z8phWamKsASZxJ0VWuiPm3GS/8g= : ~draft-7
sth1.roughtime.netnod.se: 9l1JN4HakGnG44yyqyNNCb0HN0XfsysBbnl/kbZoZDc= : ~draft-7
roughtime.cloudflare.com: 0GD7c3yP8xEc4Zl2zeuN2SlLvDVVocjsPSL8/Rl/7zg= : ~draft-11
time.txryan.com: iBVjxg/1j7y1+kQUTBYdTabxCppesU/07D4PMDJk2WA= : ~draft-11

A few months ago, there was another server that I believe was maintained by Marcus Dansaire, but as I understand it, the company providing the hosting ceased operations before summer, and the server went offline last month. Maybe Marcus will bring it back online in the near future.
That server was: roughtime.se: S3AzfZJ5CjSdkJ21ZJGbxqdYP/SoE8fXKY0+aicsehI= : ~draft-12

I also heard that some folks at Google were planning to run a Roughtime server once the protocol reached a more stable version, though I’m not sure if they’re still considering the current draft-14 version as a suitable candidate.

Best regards,
Alexandre

Sorry for the late reply.

The server at roughtime.se is still alive, with the same public key as always. There has been no downtime.

There may be two reasons for why the server appears offline. The first is that it only responds to requests with the format and version specified in draft-12 and later. Other requests are silently dropped. The second reason is that there are no routes to the server's network that go through Telia/Arelion (AS1299) networks. If you can access the web site at https://roughtime.se, the routing works fine.

Clients known to work with draft-12 and later include Pyroughtime (https://github.com/dansarie/pyroughtime) and Roughenough (https://github.com/int08h/roughenough).

Kind regards,

Marcus
