Availability issues

Bitbucket has recently become highly problematics to use. I would like the following as problems:

1. Much slower to push and pull to git repos. These often result in various errors listed below:
2. Getting various error messages:

1. • fatal: Couldn't find remote ref XXX
   • fatal: The remote end hung up unexpectedly
   • ssh_exchange_identification: Connection closed by remote host
     fatal: Could not read from remote repository.

Such errors are impacting our companies productivity.
