Technical bulletin (09/07/2004) to all our customers
Since August 23, 2004, the servers on the Equifax Canada UAT environment have been upgraded to Windows 2003.
-------------------------------------------------
Change of IP addresses for www.equifax.ca
-------------------------------------------------
As part of the Upgrade of the Operating System from Windows NT to Windows 2003, the IP of the Equifax Web site, www.equifax.ca, will change from (204.19.232.35 and 207.96.239.3) to (204.19.232.39 and 207.96.239.5) respectively.
This will not have any impact on customers accessing Equifax Canada by name only or by IP address only. Customers can still have access to Equifax using 204.19.232.35 or 207.96.239.3.
However, the customers that access Equifax Canada by name and IP address combination, will be impacted as per the following 2 scenarios:
1. The customer workstation/server is accessing by name (www.equifax.ca) and the customer firewall allows access to the IP addresses of Equifax;
2. The customer workstation/server is accessing by IP addresses and the customer firewall allows access by name (www.equifax.ca).
Unless you make the necessary adjustment for the above 2 scenarios, your configuration will disallow access to Equifax Canada after September 19, 2004 since the name and IP address will not match.
Customers that fall into one of the above scenarios will have to change the IP addresses to (204.19.232.39 and 207.96.239.5) or access Equifax Canada by name only (www.equifax.ca) or by IP address only prior to September 19, 2004, date Equifax Canada will migrate the production environment to Windows 2003.
-----------------------------
STS over the Internet
-----------------------------
Customers that POST STS transactions to the Equifax Web site must ensure that each line they POST is ended by a carriage return and a linefeed (CRLF - 0x0d 0x0a). If they terminate their lines with only a linefeed (LF - 0x0a), their transactions will be rejected by the Windows 2003 Web server with a "400 Bad Request" error.
This is because IIS 6, the Web server running on Windows 2003, strictly enforces the HTTP standard that requires each line be terminated by a carriage return and a linefeed (CRLF - 0x0d 0x0a), unlike IIS 4, the Web server running on Windows NT.
All customers doing "STS over the Internet" should test their application on the Equifax User Acceptance Testing environment at https://uat.equifax.ca prior to September 19, 2004, date when Equifax Canada will migrate the production environment to Windows 2003.
