The LINKcat PAC will be down for the 4.16 upgrade starting at 9 pm on Monday, July 22. Users who try to access LINKcat while it is down will see a "downtime" message. It will come back up by 7 am on Tuesday, July 23, barring any unforseen problems with the upgrade.
A slide announcing the downtime has been posted as part of the slideshow on the LINKcat home page. The downtime will also be publicized using the LINKcat Facebook and Twitter accounts. Messages will be posted prior to the start of the downtime and will also be posted when LINKcat comes back up.
