ITS will be upgrading our Ezproxy system tomorrow at 9 am. This will mean that links to our databases, ebooks and ejournals will fail. If you need to get in during that time, you can remove the ezproxy link from the start of urls to connect on campus.
However, although ITS have allowed 60 minutes for this, previous upgrades have caused an outage of less than 5 minutes and I suspect the same will be true for this upgrade. So unless access is urgent, you might just want to wait and try again in a couple of minutes.
