TYLER (KYTX) - The City of Tyler IT Department will be making necessary upgrades to the network on Feb. 5, 2014. The Upgrade will begin at 12:01 a.m. and should take approximately four hours.
The upgrade will affect all City systems. Employees will not be able to access any City systems or resources. Citizens will not be able to access any City websites or online bill payment systems.
