If you’re looking to call into the Chatham-Kent Health Alliance tonight, you may be out of luck. 
The CKHA is shutting down the phone system, local computer servers and the Regional Data Centre from 9pm tonight until 7am on Thursday for some routine maintenance.
That means during this time phone calls to the hospital will either get a busy signal or an automated power failure response.
Some of the lights at the Chatham campus will also be out.
There will be staff on hand to help people navigate the dark parking lots.
