# SIMnet Maintenance Notice – 12/26/2017-1/1/2017

SIMnet will be unavailable each morning from 3:30-6:30AM Central time on December 26, 27, 28, 29, 30, 31 and January 1st. This maintenance has been spread across multiple days to avoid a longer, single day maintenance window. We are performing routine maintenance to improve performance, reliability and security.

Sincerely,

McGraw-Hill Product Team
