A few things:
1) I can get to heynowlife.org without any problems, on FiOS. My IP address is 173.74.7.1xx (last two digits not shown).
2) The way you describe the problem it really does fit the IP address change and bogon filter settings scenario.
3) Verizon is in the process of distributing a new level of the software in the Actiontec routers. Assuming that you have an Actiontec router, it is likely that your router was rebooted when that new software was installed, and you got a new IP address that is left in some filters in routers somewhere between you and heynowlife.org. The new software level is 40.21.10.2, you can check to see if that is what you have. Mine was installed on my router in early November I think (at least it has been up for 33+ days, and I have not manually rebooted the router in months).
4) It is likely that many, maybe all, of the FiOS customers in your area got the new software level in the router the same night, and all got new IP addresses, and those IP addresses were all in the same range (at least some of them, check with others to compare with yours).
5) Tracert is not really a good tool to identify where something in the network is blocked or lost. Many servers are set to ignore those kinds of requests.
6) What I suggest you do is check to see what your IP address is now, then turn off the router and wait 10 to 30 minutes or more, restart the router and check the IP address to make sure it is different (and check access to heynowlife.org). If you still have problems, repeat, and keep repeating until you get an IP address way different from what you have now.
I realize that the above seems time intensive and kind of silly, but if it really is your IP address being blocked, eventually you should get one that is not blocked. Or you can just wait, eventually the filters will get updated to remove the block you are on (but that can take days, weeks, even months I guess).
Sorry, but this is the only suggestion I can make. I hope you get past this problem.
