Hi all,
In order to upgrade the kernels of various analytics hosts, we have to
reboot the machines, which will make several analytics clients temporarily
unavailable.
The maintenance will be Friday at 17:00-19:00 UTC (10am-12pm Pacific).
While this is happening, the following hosts and services will be
temporarily unavailable for a few minutes at a time:
- stat machines (stat1004.eqiad.wmnet etc)
- superset
- turnilo
- hadoop UI, druid UI
If you are planning a long-running query that will overlap with that time,
let me know as soon as possible and we'll find a resolution. Respond to
this email or come visit us on IRC at #wikimedia-analytics on libera.chat.
Regards,
Razzi
