1/ The Credentials feature on XRPL is now live! It gives developers and businesses a way to handle identity checks and compliance requirements directly on-chain, without the need to manually approve each account one by one.

After four days of solid operation, I've restarted my hub on 2.6.0 and am ready to consider it in production. At this time, there is no need for peer reservations as the hub is not even close to capacity.

For those running an XRPL node, the hub's hostname is "hub . distributedagreement . com" (without the spaces). The peer port is 51235. The "peer_private" flag will be respected for those peers that set it.

After a week of solid operation my hub had a rough day. But it was for a very good reason -- the switch it's connected to received a massive upgrade and my bandwidth measurements are much better now. These images so the solid operation. 1/2

And here are the two maintenance windows. Fortunately, all is even better now and I expect to consider the hub in production very soon. 2/2

We can fight each other or we can align against those who think people shouldn't be allowed to make their own choices. Do we want to repeat the mistake that got us into the mess Trump's getting us out of?

Last three days look good and my hub should be ready to be considered in production next week.

I'm puzzled (though not concerned) by the latency spikes. They only occur when outbound bandwidth usage is higher than usual (though its always well within what the system should easily handle) but do not occur every time outbound bandwidth is higher than usual.

I'd be a bit concerned if the 10% latency line ever hit 200ms. That still wouldn't have a real-world impact, but would be concerning. Since I restarted the server five days ago, it's never gone over 33ms.

Yay! I wish more State courts would robustly enforce the Eight Amendment's prohibition on excessive fines and penalties. Totally right here.

Here's the past 24 hours. All good. There is one spike in latency that only affected a few links that were already poor. The tiny drop in network b/w appears to be a monitoring dropout and doesn't show on the switch port's monitoring. I think we're nearly production ready.

I included the bandwidth chart twice and forgot the peer disconnection chart! Fortunately, it's very boring.

The past 24 hours of the hub's performance looks solid. There's a tiny glitch at 12:58 that might be the monitoring system. Currently it's handling 11,000 requests per second from 173 peers with about 0.006 seconds from the average request coming in to the reply going out.

I think the glitch was just one minute where for some reason the monitoring system didn't gather data. I'm working on some improvements to the collector that might fix this, but it's not likely a hub issue.
