Dear Customer,

After the maintenance from this morning one of the core switches lost all connectivity.
We are currently still investigating.

[UPDATE 11:23 EDT] As both of the core switches are reloading, our vendor advised us to downgrade the software version. We are currently in the downgrade process.

[UPDATE 11:41 EDT] One of the coreswitches has been reloaded with the other software version. The other coreswitch is still having troubles booting the older software version.

[UPDATE 12:15 EDT] Both core switches are back online on the previous software version and stable. We are still investigating intensively with our vendor. A preliminary RFO will be available from the account managers later today. Our apologies for any inconvenience caused

[UPDATE 07-25-2013 05:20 EDT]
We are having some issues with network connections between customers rack.
This problem is related to the changes made yesterday with the software upgrade.
Our apologies for any inconvenience caused and update will follow.
