Can you also post your ssh_config from your machine ? From your output above looks like your ssh ke to the bastion is not right. If this key worked from jupyterhub then most likely your local ssh config may be incorrect.
@prateek. Arash is right on this. It all depends on what kinds of aplication and your experiment is. PTP is helpful when clock synchornization is needed down to a micro/milli second level between multiple nodes that may or may not be geographically distributed.
Yes there was a power outage around that time. All nodes and VM have been restored. Please try again now.

Have you tried uploading your files directly to your FABRIC VMs ?
Do you mean that firs t instrumentized the slice, then logged out and came back and tried to re-instrumentize the same slice ?
Hello,
I looked at your nodes, but as I mentioned earlier, the relevant log files are on your jupyterhub session in /tmp/mflib/*. We would require those to look into the cause. I tried the same slice using my account and have not encountered the error you mentioned.
All slices have been recovered and the site is functional again—apologies for the inconvenience caused.
Try now. My colleague Mert Cevik has restored all VMs. But FYI any data-plane interface config that was not persistent may need to be re-created
The FABRIC SALT suffered a power outage last night. We are in the process of recovering the VMs. I will update you once they are up again.
Is this slice still active? If so, could you please let us know which rack it is on ?. Also it would be good if you can also send us your MFlib log file which should be in /tmp/mflib/* on your jupyterhub session.
This is just a guess, but in your commands to delete IPs, you are deleting the IP/interface that you SSH into thus killing your SSH connection to the VM.
Hello,
TACC being our of IP is out of our hands for now due to the limited IPv4 space available. Hopefully, by Fall, the rack will be converted to using IPv6 which would resolve this issue.
BRIST had a data plane outage today (07:00 BST and 09:00 BST Tuesday 4th June 2024.). Apart from these, we are unaware of any other issues. We will need more details about the nature of the error to investigate further.
