Hello,

I'm having some connectivity issues between amd214 and amd218 following the power outage this morning. I'm not able to ssh between the two nodes. I can ssh to each of them from outside the experimental network. I've verified both network interfaces are up on the node and tried manually rebooting each node.

Thanks for you help!

Hi John,

Thanks for the heads-up, we'll take a look at it and let you know when it's back to normal.

Also in general, when you are having issues with your experiment, please link the experiment status page. It makes it easier for us to track problems down.

Thanks John!

This one ended up being pretty easy, it was my bad. I missed writing the config on one of our experiment switches as we were preparing for the shutdown, so that one switch came back up with stale state. We just finished cleaning up the switch, and I've got a ping running over your experiment net connection again, so you should be back in business. Let us know if you are still seeing any problems.

Best,
