For example, many organizations have expressed a concern that poor DHCP performance could be the weak link when thousands of customers come back online after a failure event.  If DHCP address requests are handled in a slow or scattered manner, servers will not be able to service all requests in a timely fashion.

More Kudos for Cisco.com Global

Cisco.com was just once again rated in the upper stratosphere of global web sites – just behind Google and Facebook. In the respected ByteLevel Research Web Globalization Score Card for 2012, Cisco.com grabs a very nice #3 ranking among 250 web sites for global corporations.  Cisco has consistently held this #3 position overall since 2007.

Also exciting for our global team, Cisco is specifically called out as a regular of the top globalization list: “Companies like Cisco, 3M, and Samsung have become regular faces in the top 10.

It takes an incredible amount of energy to design and regularly update our major 85 regional sites, and our Cisco.com Global Team works literally around the clock to keep things humming  (I know that for sure because I am always invited to attend their midnight and 6 AM meetings!)

You can read a little more about the 2011 Web Globalization Score Card at ByteLevel Research’s web site.
