Our IP has been blocked to use www.hebcal.com

PBX PA 4 days ago updated by Michael J. Radwin 4 days ago 1

Dear Team:

  We found today that our IP address has been blocked to access www.hebcal.com, specifically to get the parashat for a specific date like https://www.hebcal.com/converter?cfg=json&date=2026-01-21


We are using this call to display the right hebrew date and parashat and events in our Shul.


Please let us know what we can do to unblock our IP 23.23.30.32.


Best regards,

We are not blocking your IP address.

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.
