Michael Geist has the scoop at “Telus Blocks Subscriber Access to Union Website.” Short version: Telus and their union are fighting. Telus has chosen to prevent their customers from reaching “Voices for Change, the union website.
I urge Telus customers to call and customer support and ask what’s up. Repeatedly. Voices for change also suggests that Telus customers “TELUS customers can pass this proxy URL to TWU members they know who uses TELUS as their ISP: http://vfc.proxy.pfak.org/.” I’ll also suggest that TOR would be a fine way to bypass Telus censorship until you can get a decent ISP.
