Incident Report

Summary AI Generated

Webex services in the US region experienced widespread degradation for 16.2 hours, affecting login capabilities across Webex App, Control Hub, and Developer Portal, along with intermittent call failures, messaging delays, meeting feature malfunctions, and Contact Center agent login issues. The incident also impacted device pairing, voicemail services, call recording functionality, and caused some degradation in other regions due to US dependencies. Engineering identified and resolved the core issues, with Contact Center agents requiring browser restarts to restore full WebRTC functionality after the fix was implemented.

Engineering is investigating an issue impacting Webex services hosted in the US region. Users and administrators are experiencing intermittent failures across several Webex services, including logging in to the Webex App, Webex Control Hub, and Webex Developer Portal. Some Webex Calling users are encountering intermittent call failures, while a subset of callers may experience issues connecting to the Webex Contact Center. Additionally, delays or failures may occur when sending or receiving messages in the Webex App, and users are unable to log in to https://developer.webex.com/. Some users may observe split meeting conditions when joining from video devices or using SIP connections, as well as failures when utilizing in-meeting features such as content sharing, mute/unmute, and roster updates. Webex Contact Center agents may be unable to log in to Agent Desktop services and may experience intermittent call delivery failures. We are working towards restoring services and apologize for the inconvenience this may cause.

Engineering has resolved the issues impacting Webex services. US-based Webex Contact Center agents experiencing WebRTC-related issues-such as login failures, desktop telephony selection errors, or difficulties placing and answering calls-should log out of the Agent Desktop, close all browser windows and tabs, and then relaunch and log back in to restore full functionality.

We will continue to monitor to ensure service stability.

Engineering has identified the issue and continues to work toward full restoration of services hosted in the US region. Further investigation has determined that this service degradation is also impacting users in other regions. Although the impact is exclusive to the US region, some services in other regions are dependent when connecting to the US and may show signs of degradation. Also, in addition to the previously identified impact, Wholesale and Webex for BroadWorks customer and user provisioning are also affected.
