I tried to install cocoapods on mac according to the instructions http://cocoapods.org/ , but got the error as below:

$sudo gem install cocoapods

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
bad response Service Unavailable: Back-end server is at capacity 503       (https://api.rubygems.org/api/v1/dependencies?gems=cocoapods)

but sometimes, the error message is different。
