Project news

On behalf of all the members of the CPDN team I should like to wish you all a very happy Christmas. It has been an eventful year at CPDN. Andy and I have spent most of it wrestling with hardware failures, software misconfigurations, storage issues etc. Throughout this period we've had pretty solid support from all of our volunteers who have crunched their way through over 100 billion CPU cycles, donating the equivalent of thousands of years of CPU time to climate science research. Thanks again, and see you in the New Year. Jonathan Miller CPDN SysAdmin

CPDN will be taken offline at 9.00 am GMT on Thursday 10 November 2011. This is to facilitate the relocation of our project servers. It is anticipated that the downtime will be for no longer than 48 hours, but the project should be considered 'at-risk' until noon on 14 November 2011 GMT.

We apologise for any disruption, the project suffered a security incident after which we were forced to take the project down whilst we investigated. This incident has now been fully investigated. We are pleased to announce that the project is now back online again and functioning. For more information please see:

On 18 October 2011 the CPDN project server was attacked.

We have had to respond by taking the project offline.

I will provide more info as I have it, but I will be devoting my time to fixing the issues and determining the extent of the problem.

On behalf of CPDN I should like to apologise for the inconvenience this will cause

The problem with the upload server has been resolved. The server suffered 2 disk failures, which lead to the Raid array going offine, taking the webserver with it.

This has now been fixed, and uploads should be functioning normally.

Please accept my apologies for the loss of service

Jonathan Miller, CPDN Sysadmin

One of the project servers has gone offline with a major disk problem. This will primarily affect those people processing the regional model (WeatherAtHome; Hadam3p), because certain upload files are set to be received by the server Uploader1.atm.ox.ac.uk. There may also be problems accessing file downloads from this server The earliest fix date for this is tomorrow (4 October 2011) afternoon (GMT), assuming that the replacement disk arrives on time. Please accept our apologies for the disruption.

The project server is online and running, having been rehoused in a new datacentre. There are a number of issues relating to trickles and credit allocation, but CPDN staff are looking at these as I write. If you are experiencing any problems with the CPDN project please do let us know by posting on the user support boards. Jonathan

We apologise for the continuing problems connecting to climateapps2, the CPDN scheduling server, which has suffered from further problems after the recent repairs. We are giving our full attention to this matter and will endeavour to put a fix in place as soon as possible.

After the unscheduled emergency downtime of the project, we would like to announce that the main project server climateapps2 is now back up and functioning again. During these last few days we have been gradually restoring services to the project. We would like to thank all participants for their patience during this downtime period. Andy Bowery CPDN Technical Coordinator

It is looking extremely likely that climateapps2 will require an emergency shutdown this afternoon (11 July 2011) at 15.00 BST. We do not know how long the server will be down, but it is possible that it will be for several days. Obviously the BOINC forum will be unavailable during this time. I will endeavour to keep everyone informed of the status of the repair. Please accept my apologies for the inconvenience. Jonathan Miller CPDN SysAdmin
