Agenda
======

 * New infra status page (https://status.documentfoundation.org , powered by cachetHQ)
   + https://redmine.documentfoundation.org/issues/1079#note-20
   + Meant to give users a quick overview (HTTP status and response time
     only), not to replace the more comprehensive internal infra metrics
   + Atom & RSS feeds, email subscription
     → best not to subscribe using a TDF-hosted address!
   + 24 HTTP sites monitored at the moment; more can be added later
   + Metrics and outages are automatically filled using the cachet API and
     https://github.com/CastawayLabs/cachet-monitor; scheduled maintenance can
     be added too, and text/status can be edited manually to inform the
     community about our progress in solving an issue
   + Current limitations:
     - no v4/v6 distinction; ideally the component state would change to
       “outage” if IPv6 (resp. v4) connectivity is broken, assuming there is
       an AAAA (resp. A) record
     - while traffic is not routed privately, DNS queries are; better to use
       upstream DNS servers instead, and use gustl for .tdf only
       → solutions: use systemd-{networkd,resolved}, or a local caching
         recursive resolver
     - would be nice to get SMTP & IMAP status codes, too
   + TODO: add a CNAME + 301 redirect for status.libreoffice.org
   + TODO: subscribe IZBot to the feed. Can cachet push updates to it? Brett:
     don't think so
   + Officially announce the page at LibOCon, but folks can subscribe already
 * Prometheus alert system (Brett)
   + Merged and deployed; only email notifications for now (no SMS)
 * Prometheus: downgraded node-exporter from stretch-backports to stretch on
   the monitoring box
 * Upgrades:
   + Question: status of tb31.libreoffice.org? (last Ubuntu — 14.04.5 LTS —
     box, would like to align on our current — Debian 9.4 — baseline instead)
   + 37 boxes still on Debian Jessie (24 prod boxes incl. 3 hypervisors), need
     to be updated before the end of year ideally
     - some of these require more work (not based on the Jessie baseline), eg
       dashboard (vm167)
     - tentative plan: migrate the dashboard to vm213 (fresh Stretch VM)
       during LibOCon
   + upgraded gerrit to stretch last week (got rid of salt states gerrit vs.
     gerrit.prod), improved systemd unit files
 * Single Sign On
   + Auth method switched from SilverStripe's own backend to SAML 2.0 on the
     LibreOffice & TDF websites (SS3/newdesign)
   + Working on the migration for the blog's (WordPress) auth backend now
 * Next call: Tuesday October 16 2018 at 18:30 Berlin time (16:30 UTC).
