IPS Signature Update today caused DNS/Server issues

Anyone else have this issue today? Around 12 PM Central Time, the IPS Signature was updated to 18.147 and then immediately most of my work laptops would not print or connect to servers. Using Traffic Monitor, I was able to see that Signature ID 1112378 was being DENY-ed. Once I created exception, things were normal again.
