Announcement #129

DELTA infrastructure maintenance

  • Date Posted: 3.1.17

DELTA systems staff will be performing a series of maintenance items starting the morning of Monday, March 6th and continuing through noon of Tuesday, March 7th. While we do not expect any major outages of DELTA services such as WolfWare, Moodle, or Mediasite, there will be several short outages and/or periods of sluggishness and instability during this time.<br /> <br /> Our expected schedule is as follows: Monday morning: DELTA staff will be applying firmware updates to our storage arrays. This is expected to cause 30 - 60 minutes of sluggishness in DELTA services.<br /> <br /> Monday afternoon: DELTA staff will be updating the PHP version on the servers, rebooting Linux servers to apply the latest kernels, moving our primary MySQL database to a new server, and updating the Microsoft SQL Server (for Mediasite) to the latest version. This work will cause several short outages (~5 minutes) to WolfWare and Moodle while critical servers such as databases reboot. Mediasite will experience a short (~15-20 minute) outage during the SQL Server upgrade.<br /> <br /> Tuesday morning: updates will be applied to the F5 load balancers. This will cause a brief outage of all DELTA services.
