Our NOC provider FireHost has announced emergency maintenance on their system. Here is the information that have provided us:
Tuesday, October 18th 2011 12:00 AM CDT (Midnight, 2 hours)
At this time, we will be performing router configuration maintenance on the primary edge routers at our Richardson, TX facility. This maintenance is to prevent future intermittent connectivity issues as occurred at 11:04 AM CDT on 11/17/2011.
The anticipated maintenance window is two (2) hours, and service for your Secure Cloud Servers is not expected to be affected. The scope of any interruptions that occur should be limited to a brief loss of network connectivity while BGP routes reconverge. If this configuration change should be unsuccessful we will immediately roll back the change.
Please note, additional status information can be found on their main status blog
