1031305 - Capacity server URLs are dead and prevent connection

Status: RESOLVED FIXED

(Chat Core :: Yahoo! Messenger, defect)

Description

[Quentin Headen [:qheaden]]

When signing into your Yahoo messenger account, the PrPl needs to contact a Yahoo capacity URL to determine which messenger server is available for the user to log into.

The current URLs we are using seem to have gone dead, and they need to be changed so that users can continue logging into their accounts.

I was curious if the round-robin just supplies the same IP (as one of the choices) as this domain, but it does not:

Attachment: Patch 1

This patch changes the Yahoo capacity server URL to one that is set up to be redundant among their multiple capacity information servers.
