#4353 cannot browse site after posting comment

[unfunk]

After submitting a comment, I am unable to browse the slashdot website or ping its server until such time as I restart my modem.
This is regardless of OS and browser. I have contacted my ISP about this, and they suggested that it could be my modem storing incorrect routing information that gets cleared after a reboot, however I have since isolated the cause of the issue to submitting comments on Slashdot.
