12月25日Web应用防火墙全球回源网段升级扩容通知

【阿里云】【WAF】【升级通知】
升级窗口:北京时间2018年12月25日 10:30-12:30
升级内容:Web应用防火墙(WAF)国内、海外机房升级扩容
升级影响:Web应用防火墙将进行升级扩容,涉及到回源网段的扩充。如果您当前源站有设置IP白名单或者是安全组,仅允许WAF的IP回源网段访问,则需要在此次扩容前,对这批回源网段白名单进行更新。本次除了新增回源网段,还对历史网段进行了更新,请仔细核对。

全量的IP回源网段目前已在Web应用防火墙控制台上有显示。您也可以查看产品帮助文档链接获取:https://help.aliyun.com/document_detail/99399.html
随着产品回源网段的不断变化,我们建议用户不要仅以IP回源网段来做源站保护,可以选择通过流量标记的方式进行对流量是否经过WAF防护的判断,具体可参考:https://help.aliyun.com/document_detail/99413.html
