Deleted, not broken
Most unreachable leagues in this directory are casualties -- a host redirected, a certificate expired, a platform fell over. This one is different. The hosting service is running perfectly well; several other leagues in these records are served from it today. What it says about Bux-Mont is 404.
That means the site is not down. It is gone: either removed by the platform for non-payment, or taken down by whoever ran it.
Bux-Mont is how Bucks and Montgomery counties north of Philadelphia name themselves collectively, and a league using that name is claiming a specific and populous piece of southeastern Pennsylvania.
Whether it still plays cannot be established from anything published. A High Cheese league page is an address the league owns rather than an account on a service that can revoke it -- with the schedule, the standings and every roster rendered as pages that stay up because the league, not a vendor, decides they do.
