在使用虚拟主机或者租用主机又或者主机托管，由于物理距离上的限制，无法知道网站的访客访问的速度如何。这时候需要借助别的一些提供在线ping服务的网站。
下面列举一些：
提供了
| Domain or host name: | ||||||||||
| Port number: | ||||||||||
|
| ||||||||||
等服务。
提供了和ping.eu类似的服务：
| Express | URL Unencode URL Encode HTTP Headers SSL E-mail Validation |
||
| DNS Records Click here for advanced NSLookup DNS tool | |||
| Network Lookup |
just ping的服务就跟名字一样了，只提供ping服务，不过ping的结果比较全，是来自世界各地的。
