Hi all,

as part of https://phabricator.wikimedia.org/T76348 the Analytics team is going to re-image stat1001.wikimedia.org with Debian Jessie.

The activity will start on Monday May 2nd at 14:00 PM CEST (UTC+2).

Three major services will not be available during the downtime:

- datasets.wikimedia.org - stats.wikimedia.org - metrics.wikimedia.org (also known as metrics.wmflabs.org)

Notable consequences:

- Datasets will not be available for download; - Dashboards using data from datasets.wikimedia.org (most dashboards) will not have data during this period; - Some html reports may not be available (examples: vital-signs.wmflabs.org, browser-reports.wmflabs.org, mobile-reportcard.wmflabs.org, ee-dashboard.wmflabs.org/dashboards/enwiki-features, edit-analysis.wmflabs.org/compare)

The downtime should last a maximum of four hours, but please refer to the aforementioned Phabricator task for up to date timings and information during the next days. A backup will be done before starting including all the home directories.

For any issue or queries please reach out to the Analytics team mailing list or join the #wikimedia-analytics IRC channel on Freenode.

Thanks!

Regards,

Luca
