“Why I’m an Infinite Networks client, and why I tell other businesses about Infinite.”
Infinite Networks supported us as we deployed our Canberra and Brisbane teams remotely to work from home. Our need to be operational before a Monday saw Infinite team members deliver critical devices to private addresses after hours on a weekend.
