Verizon: Fiber or Die

dynamator writes: "I live about 1800 feet from my Verizon central office. I pay for their higher tier 'Power Plan' DSL service which boasts 3 Mbps up and 758 Kbsp down. For the past year, I've enjoyed excellent performance on this line. However, this past month Verizon has been hooking up my neighbors with FiOS, their new fiber-to-the-home system, and guess what, my connection speed and dependability has taken a nose dive. What can I do to build the case that this really happening? Will anyone, least of all Verizon, give a rat's ass? Are they making me a fiber offer I can't refuse?"
