Update to high-performance data transfer services
Dear users,
As previously announced, we are making further changes to some data transfer services:
ftp.ceda.ac.uk (CEDA Archive FTP server)
The new host for this service will operate at the same name ftp.ceda.ac.uk, but if you have used the hostname ftp2.ceda.ac.uk directly, then you are advised to change to using the alias ftp.ceda.ac.uk so that the change happens transparently to you when the old server is decommissioned. JASMIN GridFTP Server Globus Endpoint
The Globus endpoint will change to a new server on Tuesday 2nd March. If you are using the “JASMIN GridFTP Server” Globus endpoint via Globus web or command-line interfaces, the endpoint ID of the service will remain the same but the server at the JASMIN end will change. This should only affect transfers in progress at the time of the change, so impact should be minimal given that this coincides with the planned maintenance day already announced.
However, if you use certificate-based gridftp (gsiftp) directly i.e, not via Globus Online interfaces, but with the globus-url-copy client, then the hostname data-xfer1.ceda.ac.uk will need to be replaced with gridftp1.jasmin.ac.uk in your gsiftp:// URIs. All other aspects should remain the same. We are still investigating an issue affecting transfers to and from some file system (particularly affecting transfers made using Globus) and this is still not yet fully resolved.

Reminder Notice JASMIN System Maintenance Tues 2 March 2021
Scheduled maintenance is planned for Tuesday 2nd March 2021, which may cause some disruption to JASMIN and CEDA services.
On a regular (roughly quarterly) basis, important updates are applied to systems within the JASMIN infrastructure (which also hosts the CEDA Archive and associated services) in order to keep them up to date and secure. Some servers may need to be rebooted in order for these changes to take effect, so there may be an interruption to some JASMIN and CEDA services on this date.
Other work may also be scheduled for this date in order to minimise disruption to users.

Reminder Update to high-performance data transfer services
Dear users,
As announced last week, the following servers will be decommissioned tomorrow Friday 12th Feb:
jasmin-xfer[23].ceda.ac.uk (high-performance data transfer servers)
now replaced by hpxfer[12].jasmin.ac.uk: please use these instead. ftp.ceda.ac.uk (CEDA Archive FTP server)
The new host for this service will operate at the same name ftp.ceda.ac.uk, but if you have used the hostname ftp2.ceda.ac.uk directly, then you are advised to change to using the alias ftp.ceda.ac.uk so that the change happens transparently to you when the old server is decommissioned. We have been aware for a while of an issue affecting transfers to and from some file system (particularly affecting transfers made using Globus) but this is still under investigation. Please look out for further announcements about this and replacement of the remaining high-performance data transfer servers.
