I thought it was the first three letters of the URL.
I thought I saw a list somewhere on here or docs.
Some are self explanatory: app-lon is london for instance.
But what about app-e or app-abc ?
I'd love to see the list, but I haven't seen one before. I'm sure Marketo has one, but not sure that they would actively provide that list. "app-e" I've seen as Europe.
Are there more than one per time-zone?
I'm on app-ab*, but wondering if there are other options in Easter Standard (New York) Timezone?
I doubt they're going to let us crack the code on this one, but you can ask support and they typically know what you're on.
