This guide is put out by the Michigan Department of Transportation. Some good useful stuff in here that applies to all fiber contractors. It’s a good quick read for those of you getting into fiber. You can skip over large sections and still get some information out of it.
Geospatial Utility Infrastructure Data Exchange (GUIDE) creates an organized and sustainable approach to data collection, management, and dissemination of 3D geospatial data on underground utility infrastructure by capturing accurate XYZ information at the time of installation and organizes it in a spatial database format for secure, highly accessible use by downstream stakeholders.
I started a blog tonight on DNS design for the ISP. As a result of this writing, I found myself explaining a lot of what the following video does. So if you are not familiar with how DNS works please watch the following video and look for a new post soon on DNS design for the ISP.
