[jira] Commented: (INFRA-3122) a certain block of facebook.com machines is unable to access svn.apache.org

["John Sichi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/INFRA-3122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12925695#action_12925695 ] 

John Sichi commented on INFRA-3122:
-----------------------------------

Example failure (after hanging for a while):

[njain@devrs005 hive1]$ svn up .
svn: OPTIONS of 'http://svn.apache.org/repos/asf/hive/trunk': could
not
connect to server (http://svn.apache.org)

Attempts to telnet to the svn server (port 80 or 443) from the affected machines also hang and eventually fail.  Trying different svn mirrors did not help.

Note that there's a good chance the problem is within Facebook; we're just trying to rule out the possibility that these machines somehow got blacklisted.

> Yesterday morning, Hive and Hadoop developers at Facebook started experiencing failures attempting to run svn to svn.apache.org from certain machines.  Other machines within facebook.com are not having the problem.  Facebook network engineers are investigating the problem but so far have not been able to locate a cause of the problem within Facebook's own network.  The affected machines happen to be development machines which happen to make heavy use of svn.apache.org, so we would like to know whether there's a possibility that the affected machines somehow got blacklisted by the svn servers (e.g. via some automatic defense against denial of service attacks).
> The affected block of machines NAT's to the following IP address range.
> 69.63.179.33-35
