Bell MTS has reserved these blocks of time for regular Internet and TV network maintenance that may impact Internet service:

Sunday, Tuesday and Thursday mornings, between 1:00 am and 6:00 am

Depending upon the equipment affected, customers may experience minor service disruptions during these hours. As such, you may wish to avoid scheduling automated processes (such as billing processes for a business) at these times, to ensure that they are not impacted by network maintenance work.
