昨天下午在微信群看到消息说微软旗下的代码托管平台 GitHub 屏蔽了中国 ip 访问，对于当前已经处于登录状态的用户来说仍然可以访问，如果尚未登录则在访问时提示 IP 对该站点的访问已被限制，报 403。
GitHub Community 官方社区有关于这个问题的讨论帖子，大量开发者反馈遇到相同问题。
各种猜测……
官方刚刚不发公告：[Retroactive] Access from China temporarily blocked for users that were not logged in
「Github屏蔽了中国IP访问？：https://uxtt.com/github-block-china-ip」Incident Report for GitHub
Resolved
Due to a configuration change with unintended impact, users that were not logged in who tried to visit GitHub.com from China were temporarily unable to access the site. For users already logged in, they could continue to access the site successfully. Impact started 2025/04/12 at 20:01 UTC. Impact was mitigated 2025/04/13 at 14:55 UTC.
「Github屏蔽了中国IP访问？：https://uxtt.com/github-block-china-ip」The configuration changes that caused this impact have been reversed and users should no longer see problems when trying to access GitHub.com. Posted 20 hours ago. Apr 12, 2025 - 20:00 UTC
散了散了，洗洗睡吧……
不过该科学还是得科学加速……
