Hi Christopher and Tom, I'll reply to you together, as they seem to be along the same lines.
For the purposes of this survey/research, a reference to an LOA is a reference to an LOA for the advertisement/filtering of IP space. I agree, the acronym LOA has multiple uses in the world of IT for things such as datacentre cross-connects, however given what we are looking into, I believe its quite clear that any references to an LOA is a reference to a Letter of Authorisation for the advertisement/filtering of IP space. Other facility providers (such as Equinix, see https://docs.equinix.com/en-us/Content/Interconnection/DiLOA/xc-Loa.htm) have already started looking into the realm of digital LOAs for services such as cross-connects. While they are not the same as traditional LOAs, in my belief they are designed to reduce the timeframes in issuing them, having them sent across and completed.
