Could you explain what's behind this service ?
@danvy It's a load balancer that:
- Response validation of the timestamp reply before returning it to you.
- Automatic retrying. e.g. if one of the upstream servers returns an invalid timestamp reply, we automatically return the next valid response from the next server.
- Fans out to multiple trusted timestamping servers in parallel. The two steps above happen in multiple threads, so you will always get the fastest response possible, even if the first upstream CA returns us an error (you won't see the error, we handle that).
- Allow CORS requests.
- We update the upstream CAs in our list server-side. i.e. You should never need to update your RFC3161 URL in your application if you use any of the
https://rfc3161.ai.moda/[*]
URLs. e.g. today I noticed that IDnomic/Keynectis took their server down, but we already had 7 fallbacks forhttps://rfc3161.ai.moda/adobe
and 8 fallbacks forhttps://rfc3161.ai.moda/windows
, so it resulted in zero downtime for anyone.
Out of 1.33 million requests this month, we've had 60 errors. So roughly a 99.995% success rate.
Hi, @Manouchehri. I wonder if there is any document discribing diffrences between each suffix of https://rfc3161.ai.moda/[*]
?
