谷歌打不开 google打不开,与中国大陆封杀有关,但是主要是因为最近google服务器在全球范围内重新进行了布局调整。
解决办法是只要修改用户本地计算机hosts文件就可以了。
一、Windows系统修改hosts文件的方法
windows系统hosts文件在本地电脑C盘,路径是:C:\Windows\System32\drivers\etc 
用记事本txt文件打开hosts文件。
(如果提示没有管理权限的话,可把hosts文件复制,粘贴到电脑的桌面。在电脑桌面上双击hosts文件,用记事本打开,添加代码修改,保存,再把桌面上这个hosts文件复制,粘贴到C:\Windows\System32\Drivers\etc 文件夹里,电脑提示“是否替换”,点击“是”,替换原来的hosts文件。)
(如果没找到hosts文件,可在本帖末尾下载一个新hosts,复制到C:\Windows\System32\Drivers\etc 文件夹里。)
在hosts文件中把鼠标光标移到最下面那行代码末尾,回车换行,再添加进如下代码(代码前面不加 # ):

代码有点长,直接复制就可以。然后重新打开谷歌google搜索、Gmail邮箱或谷歌相关服务,看看是不是速度飞快呢?!
二、苹果Mac系统修改hosts文件的方法
第一种方法:在应用程序里面打开终端(terminal),输入 sudo vi /etc/hosts 回车进入。如果提示输入密码,就输入锁屏密码。hosts文件就自动打开了。
接着输入英文状态下的“ i ”,进入编辑模式,将上面的代码(和上面Windows系统的代码一样)拷贝进去,编辑完成之后,按 esc退出,输入 :wq 保存。
第二种方法:启动root帐户直接改。打开终端,输入: sudo open /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts  就可以用文本编辑来直观修改hosts了。 
三、Android手机手动修改HOSTS文件的方法
  Android手机是和Google帐号紧密联系的,很多时候Google帐号无法登录,导致Android无法使用。
  在电脑上我们通过修改Hosts方法可以解决Google的登录问题,在Android手机上也可以使用这个方法。
具体操作方法是:
  1、先通过各种方法让Android手机获取Root权限,之后运行Root Explorer管理器,进入可写状态,找到/system/etc/hosts的文件,将其权限修改为可写。
  2、打开Terminal Emulator,输入su,进入root模式,输入 vi /system/etc/hosts 命令,按i进入编辑模式,之后将需要添加的代码加入hosts文件中。
  3、Android虚拟终端下当vi在编辑模式时,按下“确定”键(Trackball),再按下虚拟键盘上的“1”,就可以退出编辑模式了(CTRL+[),这个时候使用 :wq 就可以保存退出了。
  4、之后重启手机即可。
