Good morning,
If you do not use our Archiva
<https://wikitech.wikimedia.org/wiki/Data_Engineering/Systems/Archiva>
artifact repository service, you may ignore this message.
Apologies for the short notice. This is just to let you know that I will
be performing some maintenance work on our Archiva server today, which
will result in some brief periods of downtime for the service. One
element of this work is a disk storage change operation and the next is
an O/S upgrade. I will try to keep the downtime of the service to a minimum.
Apologies if this instability causes you any inconvenience. Please do
feel free to let me know if this impacts your work and I will try to
help you find a workaround.
Kind regards,
Ben

Hello,
Just a quick reminder that this work to take stat100[4-7] out of service
will be going ahead next Tuesday morning, May 28th.
Please ensure that you have copied any important files to different stat
servers or to HDFS before then.
Feel free do get in touch with us at if you have any concerns about this
schedule.
Kind regards,
Ben
