Some ISPs block known sources of malware (spam, viruses, and spyware).
It's also possible that those sites are blocking your ISP because it has been a past source of malware.
The real problem is that some other source of malware has phaked the return address of your ISP, or of any of the other ISPs. The blocking software can't seem to tell that the address on the received malware is phake.
Another possibility is that the ISP is sleazy, and blocks any service which the ISP also sells.
Another possibility is that changing ISP settings on your browser reset your security settings, possibly to the strictest settings.
The last possibility is that something was down at the ISP.
