我在 Heroku EU 中托管了 Rails 4 应用程序。

两天后,我几乎不可能启动 Heroku 控制台。100 次尝试中有 90 次以如下错误结束:

我想知道这是否取决于我?或者这是 Heroku 认为不会再次在他们的状态页面上发布通知的广泛错误。我不确定,因为我在使用新安装的 Ubuntu 时遇到了困难。一些 CA 购物车问题...但我现在可以连接到任何人...嗯,我不确定。

我昨天在 Heroku 开了一张票,7 小时后他们的回答是“问题仍然存在吗?”。

在我将虚拟机和物理操作系统的 DNS 设置更改为使用 Google DNS 后,一切都已修复!!!!!!

ALL 是 DNS 问题...

我不知道谁对这种情况负责?它是我的 ISP 提供商吗?我该生谁的气??

这是常规的 Google DNS 设置:

8.8.8.8
8.8.4.4

这是 Heroku 上的 dyno 中 EC2 服务器主机名的 DNS 解析问题。

除非您在您的测功机上配置了某种疯狂的自定义构建包,否则这可能是他们的临时问题。
