Bill, I'll be happy to contact the IT and/or policy people at any or all of the Tribal Governments who's jurisdictions are surrounded by, or proximal to, those of the state of Utah. (a) They could use the business, just like anyone else, and (b) they are not subject to Utah's state law (and before any smarty pants says "PL 280 Utah Code Annotated sections 63-36-9 to 63-36-21, 1991", let me point out that Utah has not amended its state constitutions and, consequently, their claims of jurisdiction are subject to legal challenge, and (deep breath), PL 280 wasn't intended to help missionaries chase foul mouthed apostates and 1st Amendment exercisers out of Indian Country), and quite attached to keeping that difference and keeping it visibly.
NO, see 76-10-1233(1) "A content provider that is domiciled in Utah, or generates or hosts content in Utah, "...
