Webex by Cisco Outage History

Webex experienced intermittent poor audio quality affecting agents using Webex Calling Dedicated Instance and Webex Customer Experience services in the US region for 4.5 hours. The impact was later clarified to be limited to Webex Calling Dedicated Instance and Webex Customer Experience agents who rely on Webex Calling Dedicated Instance for audio delivery. Engineering identified and resolved the underlying issue, restoring normal audio quality across affected services.

Webex Calling experienced a 10.1-hour incident where newly registered phones failed to register for some Webex for Government users, with affected devices displaying "Webex services not connected" error messages. The issue impacted Webex Calling services and phone endpoints, preventing users from completing phone registration processes. Engineering identified and resolved the underlying issue, restoring services and continuing to monitor for stability.

Webex by Cisco experienced a login issue that prevented users from accessing the App Hub Portal, affecting the Developer API service. Engineering identified the root cause and worked to restore services. The incident lasted 48 minutes with a minor impact classification.

Partner administrators in the EU region experienced failures when attempting to generate device activation codes in Webex Control Hub, preventing device provisioning for 6.9 hours. Customer administrators were not affected by this issue. Engineering investigated and resolved the problem impacting the device provisioning functionality.

Webex Calling experienced intermittent failures when provisioning devices via MAC address in Control Hub for 1.5 hours. Users were advised to use the activation code feature as a temporary workaround while the issue persisted. Engineering completed remediation activities and restored full service, with continued monitoring to ensure stability.

Webex App users in the US region experienced intermittent call join failures and message send failures for 36 minutes. Engineering identified and resolved the issue, restoring services and continuing to monitor for stability.

Webex Contact Center experienced issues where administrators encountered intermittent failures when publishing flows, and users experienced dead air during calls for flows using percentage allocation nodes. The service disruption lasted 44 minutes before engineering completed remediation activities and restored normal functionality.

Webex by Cisco experienced a major service incident where customers were intermittently unable to load their Webex sites, preventing them from starting or joining meetings. The issue affected Webex Meetings for 44 minutes before engineering completed remediation activities and restored services. Engineering identified the root cause and implemented a fix while continuing to monitor for service stability.

Webex Calling users experienced call disconnection failures after placing E911 emergency calls, specifically affecting customers using Redsky emergency calling services on Cisco MPP phones while soft clients worked normally. The issue lasted 36.2 hours and was resolved through collaboration between engineering teams and the vendor. Service was fully restored with continued monitoring to ensure stability.

Webex services in the UAE and Saudi Arabia region experienced intermittent failures for 9 hours, affecting login attempts to Webex App and Control Hub, call failures in Webex Calling, connection issues to Contact Center, and messaging delays. Engineering identified the root cause and implemented remediation activities in phases, first restoring login services, then Contact Center connectivity, and finally Webex Calling functionality. All services were fully restored after engineering completed their remediation work and confirmed service stability through monitoring.
