Planned Server Maintenance: December 26, 2018

Server maintenance is planned for LibGuides, LibAnswers, and LibCal in all regions on Wednesday, December 26, 2018, which may cause brief downtime (no more than 15 minutes in the worst case) for a subset of our customers.

There are no changes or actions required on your side, by anyone, for any product. So you don’t have to lift a finger! This is simply a notification of the expected downtime while we update our servers. We will remind you again (via a message when you log into your system) as we approach the maintenance date.

This work is necessary to strengthen our load balancing infrastructure for all of our customers. As a reminder, we use load balancing so that any sites attempting to connect to a disrupted server automatically move to a healthy server while we replace the disrupted server. A minority of customers, however, opted to be tied to a single server due to the nature of the setup of their custom domain. Those customers will also be load balanced upon completion of this update. (If this does not sound familiar to you, you are likely not part of that minority of customers.)

We chose Wednesday, December 26, 2018 for this maintenance / brief downtime based on usage logs, which show this is one of the lowest usage periods in the entire year. We will further mitigate any disruptions by performing this server work either early in the morning or late at night in each server region’s time zone.

Please let us know if you have any questions!

    Is there a way to narrow time the time window for a specific region?

      Hello Hope –
      We don’t have specific times set for the work yet. As mentioned, we will plan to do the maintenance either early morning or at night, based on the time zone(s) for the server region (US, EU, CA) so as to mitigate the impact as much as possible. We will be posting a reminder via login message as we get closer to the date, so if we have defined times per region at that point, we’ll include them in the message. Also, only a small subset of our customers will really see the downtime: those customers who have opted to tie to a single server for their custom domains using A records. If you are curious whether or not you use an A record, you can either check in with your IT department or use an online tool like MXToolbox or UltraTools.
      Thanks!
      Anna
