Answer

Answer
Not a bug

Your DNS server is caching IP addresses much longer than it should. We changed our IP address more than 24 hours ago, and for some reason your Internet Service Provider is not respecting standard DNS Time-To-Live.

$ host www.hebcal.com
www.hebcal.com is an alias for www-vip.hebcal.com.
www-vip.hebcal.com has address 129.212.148.210


If you're running your own DNS and caching beyond standard TTLs, flush your cache. Otherwise, ask your ISP to follow Internet standards.
