Issue/Introduction

Users from one location attempting to access a website receive the network error "Operation Timed Out - tcp_error"  only for a specific data pod.  Other data pods reach the website without an error.

When you pull a report from the WSS portal, it shows Error 503 in the status.

Network Error
A communication error occurred:
"Operation timed out".
The web server may be down, too busy, or experiencing other problems preventing it from responding to requests.
Tech support information: tcp_error

Cause

The specific website has blocked the WSS data center Egress IP.

Resolution

Request the website to allow all Egress IP's from all WSS data centers or those that are closest to the location that needs access to that particular website.

See Web Security Service (WSS) ingress and egress IP addresses

It could be that the registered country information of the Egress IP is different from its actual geolocation and the website doesn't allow the Egress IP wrongly. In that case, you can check updated geolocation with the following URLs:
