Cloud returned old IP content after web server grobal IP changed.

Products

• Web Security Service - WSS

Issue/Introduction

Scenario:
I changed global IP address of our web server.
After the change, cloud service returned content from the previous IP address.
Non-cloud access returns content from the new IP address.

Cause

The Blue Coat service has a TTL base DNS cache from the server.
 

Resolution

This is not a cloud service issue.
The DNS propagation of host/IP changes normally requires 24 hrs.
 

Workaround

No workaround; wait for the finished DNS propagation.
