What was happening for ADDS/DNS there anyway that there'd be that many tombstoned DCs? How did authentication happen?
My theory is the vpn tunnels were removed, and nobody checked if there was any kind of dependencies for those tunnels.
Below is the current setup.
The replication disconnection/issue happened at Highlands with 6 of it's inbound partners. The one's with the strikethrough
FortWorth -Replicates from Highlands
Highlands -Replicates fromToronto, Edmonton, Fort Worth,Nashua,York,Fresno,New Freedom,Oakland, Atlanta, Pewaukee
Toronto -Replicates from Fort Worth, Highlands, Nashua
Fresno -Replicates from Fort Worth, Highlands, Nashua, Toronto
Pewaukee -Replicates from Higlands
Nashua -Replicates from Edmonton, Oakland, Pewaukee, York, New Freedom, Atlanta, Toronto, Fort Worth, Highlands, Fresno
Oakland -Nashua, Highlands, Fort Worth
Atlanta -Replicates from Highlands, Fort Worth, Toronto
York -Replicates from Highlands, Fort Worth
NewFreedom -Replicates from Nashua, Highlands, Fort Worth
Edmonton -Replicates from Highlands, Toronto
Okay, with that amount of time ...

Another way to achieve this goal is to extend the Tombstone lifetime with ADSI Edit. You can find the option in CN=Configuration,DC=ForestRootDomainName,CN=Services and CN=Windows NT. Right click CN=Directory Service, and then click Properties. In the Attribute column, click tombstoneLifetime and change the value. Check the event log for the last successful replication date, this is very important in deciding the correct number of days. Beware that it is possible that objects that were removed are showing up in Active Directory again! You have to be sure that there arenโt that many changes in AD otherwise you can end up with a big mess.

Emphasis mine.
Just how much change is there between then and now?
If there's a fair amount, then DCPromo -Force to remove ADDS/DNS from them and then DCPromo them back in after cleaning up the metadata, DNS, Sites, Trusts of any lingering bits and pieces.
Again, make sure there's a known good backup before starting.
