I have not been able to access these sites for 2 days. The sites are actually up, I can still access them from my AT&T smartphone. So Verizon appears to be blocking them.
I regularly need to access these sites, so I would probably need to change provider if this continues. The sites are all governmental sites, so I don't see how they could be a source of security issues.
Grateful if anyone has any clue about how to get Verizon to lift their block of these sites.

It's hard to say if it is a block or not on the IP addresses used for their sites. To me, it looks like a router somewhere took a dump and has a bad routing table. I can reach some of the gov.sg subdomains, but most of them fail to connect. My web server is able to connect to the *.gov.sg domains without an issue, and traces to them over NLayer in Chicago where I hop onto Seabone in Chicago heading directly to Singapore and hit their server with ~230ms latency (awesome routing...).
See: Hop 2 is the Verizon edge router. Hop 3 is normally the core router for the backbone in my area. Hop 1 is my router. I'm on DSL. The Final Trace route goes to a working website. Notice, I route successfully through the Verizon network onto NTT, where I eventually route to Japan and from there, Singapore.

If you noticed the name of my server, yeah I'm a gamer. Yes, it's a dedicated server and yes, it runs lots of game servers, hence the name.
For the time being, I would suggest using either your AT&T Smartphone when you need to visit the site, use a Public Web Proxy if possible, or use a VPN connection to run over another ISP until we find out what the issue is.
