Hello,

We need to plan to decommission several of the analytics clients https://wikitech.wikimedia.org/wiki/Analytics/Systems/Clients, also referred to as the stats servers, since they have reached their end of service date. The servers in question are:

* stat1004 https://wikitech.wikimedia.org/wiki/Stat1004 * stat1005 https://wikitech.wikimedia.org/wiki/Stat1005 * stat1006 https://wikitech.wikimedia.org/wiki/Stat1006 * stat1007 https://wikitech.wikimedia.org/wiki/Stat1007

If you actively use these servers, please consider moving your work to alternative stat servers (namely, stat10[08-11]) as soon as reasonably possible.

Similarly, should you have personal files in your home directory on any of these servers that you would like to retain, now would be a good time to consider moving them to a different server, or moving them to your HDFS home directory.

There are some guides available on syncing files between stats servers https://wikitech.wikimedia.org/wiki/Analytics/Systems/Clients#Rsync_between_clients and also using the hdfs CLI https://wikitech.wikimedia.org/wiki/Analytics/Systems/Cluster#How_do_I... to manage files, which may help you to clean up the necessary files.

We would like to be able to decommission these servers *three weeks' from today*, which is on *Tuesday May 28th*. Please do feel free to get back to us if you feel that this timescale will not allow sufficient time for you to migrate your work to alternative servers, or if you have any other concerns about this plan.

Kind regards, Ben
