Please be aware that due to Domain Name Server (DNS) upgrades undertaken by our host institution on 30 and 31 March 2021, there could be delays or interruptions to access to CEDA and JASMIN services after 18:00 on each of these dates. ...

The properties of our oceans are changing. The Southern Ocean absorbs more heat than any other ocean and as a consequence of climate change, it is warming at an alarming rate. Warming oceans lead to a decline in Antarctic sea ice, increased ocean freshening, sea-level rise, reduced oxygen and CO2 uptake and slow the vertical exchange of waters. This may bring about increased food scarcity, diseases, extreme weather events, loss of coastal protection, and more. It is therefore extremely important to have a detailed understanding of what could happen in the future with a Southern Ocean that is warmer, less salty and is circulating in different ways. ...

Unfortunately we are still having recurring problems with the Elastic Tape system. This has resulted in further failures of both ingesting and retrieving data. We are actively investigating this, in conjunction with our colleagues in the Scientific Computing Department (SCD). In particular our SCD colleagues have spent a lot of time trying to remedy this problem. ...

Dear users, Please be aware that due to scheduled network maintenance carried out by our host organisation, there will be a series of brief interruptions to network connectivity (a few seconds each) today, Wednesday 10th March 2021, between 09:00 and 10:30. These will affect network connections to the RAL site (and hence JASMIN and CEDA services), so may result in disconnected terminal sessions, interruptions to processing or data transfers in progress or availability of services. We are informed that the interruptions will also affect connections made using the Optical Private Network (OPN) connections to Leeds, Edinburgh and the Met Office. ...

The scheduled maintenance that happened yesterday, Tuesday 2nd March 2021, is now completed. Most JASMIN and CEDA services are back running as normal. However, there are ongoing issues related to access to MASS. We are working on resolving this ASAP. ...

Scheduled maintenance is planned for tomorrow, Tuesday 2nd March 2021, which may cause some disruption to JASMIN and CEDA 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. ...

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. ...

We believe that the problems affecting Elastic Tape and JDMA to now be solved. Users can now start using the services again. ...
