Due to maintenance windows, the CHIA-INET system may be unavailable, from 5:00 p.m. to 8:00 a.m., Monday through Friday.


How long will CHIA Submissions or CHIA-INET remain open if I do not hit a key?

There is a 25-minute time-out when a user is online. If a user does not press a key for 25 minutes, he/she will be logged out and placed back at the sign-on screen. This means that any data being entered online that has not been saved will be LOST. Therefore, users should get the information ready before logging on, and be sure to SAVE information before logging off or looking for submission information. Users can save data and reenter the online data screens many times until the data is actually submitted, so users should save data frequently during any session.
