跟进：河滨县911服务全面恢复，警长办公室确认网络故障已修复
持续了 10 月 22 日大半天的加州河滨县（Riverside County）911 服务故障已经结束。当天下午 5 时，县级警报系统 AlertRivCo 向全县居民推送公共安全警报，宣布河滨县 9-1-1 服务已全面恢复。此前几分钟，河滨县警长办公室（Riverside County Sheriff's Office）于下午 4 时 53 分许在官方账号发文称「网络故障已经恢复，谢谢大家」（Update: The network outage has been restored. Thank you!），并在原故障通告图上压印「网络故障已恢复（NETWORK OUTAGE RESTORED）」字样。
这次故障最早于 10 月 22 日凌晨显现：Palm Springs 警察局约于凌晨 2 时率先提示，T-Mobile 用户拨打 911 可能受阻；Indio 市的 911 线路约于凌晨 3 时 30 分中断；清晨 6 时许，河滨县通过 AlertRivCo 推送全县警报，称部分手机用户拨打 911 可能无法接通，并公布警长办公室调度专线 951-776-1078 作为紧急备用号码。警报范围覆盖全县，西起西南部的 Temecula 一带、东至 Blythe。故障主要影响 AT&T 与 T-Mobile 的部分手机用户，期间发送短信至 911 的求助功能一直可用，Desert Hot Springs 等城市的 911 系统则未受影响、运作正常。
关于故障原因，官方在恢复通告中未作更新说明。此前 AT&T 曾表示，通话受阻源于另一家运营商的光纤线路受损；Cathedral City 警方曾提及洛杉矶（Los Angeles）一带疑似破坏行为可能与之相关，但未获证实，官方称原因仍在调查中。随着服务恢复，居民可照常拨打 911 求助，备用专线不再需要用于紧急情况。

Follow-Up: Riverside County 9-1-1 Service Fully Restored After Daylong Outage
The 9-1-1 outage that disrupted emergency calling across Riverside County, California, for most of October 22 has ended. At 5 p.m., the county alert system AlertRivCo pushed a public safety alert to residents announcing that 9-1-1 service in Riverside County is fully restored. Minutes earlier, at about 4:53 p.m., the Riverside County Sheriff's Office posted on its official account: "Update: The network outage has been restored. Thank you!" — stamping the words "NETWORK OUTAGE RESTORED" across its original outage notice.
The failure surfaced in the early hours of October 22. The Palm Springs Police Department first flagged the problem at about 2 a.m., saying T-Mobile customers might be unable to reach 911. The city of Indio's 911 lines went down at about 3:30 a.m. Around 6 a.m., Riverside County sent a countywide AlertRivCo alert warning that some cellphone users might not get through to 9-1-1, and published the Sheriff's dispatch line, 951-776-1078, as the emergency alternate number. The alert area covered the entire county, from the Temecula area in the southwest to Blythe in the east. The disruption mainly affected some AT&T and T-Mobile cellular users; texting 911 remained available throughout, and some cities, including Desert Hot Springs, reported their 911 systems were working normally.
Officials did not update the cause of the outage in the restoration notice. AT&T had earlier said the failed calls stemmed from damage to another provider's fiber lines, and Cathedral City police had mentioned suspected vandalism in the Los Angeles area as a possible factor, which was not confirmed; officials said the cause remained under investigation. With service restored, residents can once again reach emergency dispatchers by dialing 911 as usual, and the alternate number is no longer needed for emergencies.
