Server Hippo – Network Problem

November 26, 2010 / Ahmandonk

On 11/25/2010 some users experienced degraded network connectivity stemming from a network attack that took place around the time. The incident was roughly 70 minutes in duration lasting from 6:55pm to 8:05pm CST before it was fully mitigated by our network engineers.

This attack was related to a similar attack that we observed several weeks ago and unfortunately both attacks ceased before the effects they were causing at certain points in the network could be fully analyzed. However, we have gathered sufficient data during this incident to determine the area of the network being exploited and have put additional monitors in place to assist in gathering relevant data that can be used to more quickly mitigate such an attack if it occurs again.

Dear Valued Limestone Networks Client,

You are receiving this notification because Limestone Networks has scheduled a maintenance window to perform work on several fiber cross connects which provide carrier bandwidth to our facilities. Since this will involve a minor interruption in service we are informing all of our clients of scheduled maintenance as far in advance as possible.

This maintenance window is scheduled for Friday, November 14th, 2008 from 12:00AM to 6:00AM CST. Those clients who will be affected, which is anticipated to be less than 5% of all clients, will experience a brief (5-10 minute) loss of network connectivity to their servers. We do not anticipate power loss to any servers during this maintenance window.

We appreciate your understanding and cooperation in this matter.
