All, A member of Microsoft's GNS network escalations team saw my postings on NANOG about this issue and took offense at my use of this forum to raise this issue with them, and criticized me as being unprofessional and lacking in business acumen. Therefore, I would like to publicly apologize for my actions here. It was not my intention to "humiliate" Microsoft into compliance but rather to find a means of effective contact with them since none was to be found before today. However, I recognize that I did step over the line, especially with regards to one comment I made in an earlier post about "giving Microsoft too much credit." I apologize for this and retract this, and ask their forgiveness. As I promised, I will not be posting any more to this list regarding this issue unless it is to report the final verdict that I receive from my now-open ticket with Microsoft (thanks to this list, I found an effective contact), or to discuss the mechanics of PMTUD in general.
