Emergency Network Maintenance Window September 8th 2006 22:00 CST – Sept 9
2006 02:00 scheduled maintenance window
After thorough investigation of all our existing network devices,
configurations entries and IOS software versions Cisco Systems has asked
that we replicate the error that affected our second data center location
(LT-DFW02 – Databank).
Replicating this error on site will allow Cisco engineers and our network
team to find the true cause of the problems we experienced several weeks
ago. In order to accomplish this there will be possible network related
issues during the maintenance window. Clients hosted in the following
network ranges will possibly experience packet loss, increased latency or
temporary interruption of service.
This has the possibility of affecting hosts in the following ranges
72.232.176.0 -> 72.232.230.0. If your host(s) IP’s are not in this range
your servers WILL NOT be affected. These ranges are only routed to our
second location and all hosts located in that data center are likely to be
affected. All hosts located in the Savvis IDC WILL NOT be affected by this
work.
Their will be a team of Cisco Engineers on site running active diagnostics
during this reproduction. These results will be analyzed for source causes
and devices may be replaced if they are found faulty. Their is a full
rollback plan in place to ensure that this maintenance window does not
exceed the time frame listed.
Regards,
Layered Technologies
