Will need to know the hardware version (WRT54G ver. x.y) for any firmware updates
There are too many possible cable modems offered by Optimum - I'll wait until you post the exact model to provide links for that device. Note that the full model for that device is also needed - firmware is generally controlled by the ISP (Optimum), but a reference manual is always a good thing to have.
The odd thing about this issue is that it recently began. Barring any known configuration changes, that leaves Cablevision (DNS) or firmware changes to the network devices, possibly firewall rules. There's no rhyme or reason for a single site to be affected. For it to be even further narrowed down to secure pages is quite the puzzle.
Are you the only person with the authority to change the network configuration?
If the DNS change and power cycle do not resolve the issue, then you'll have to provide screen shots or text versions (if possible) of the network device configurations. This can wait, pending the results of any outstanding tests.

- Flip the device over.
- You should find the model number on the sticker underneath the device. Please see the example.
- Take note of the exact model number and version of your Linksys device.
The serial number is located right underneath the model number.
In this example, the model number of the device is WRT54G ver 6.
NOTE: The images may vary depending on the exact model number of your Linksys Product.
If there is no version number beside the model number it means that is version 1.
