ImageSilo Maintenance Notification – May 4, 2012

Start Date: May 4, 2012 (Friday)
Start Time: 20:00 (MDT)
Finish Date: May 7, 2012 (Monday)
Finish Time: 04:00 (MDT)

Purpose: Complete work originally scheduled for April 20, 2012. An upstream network provider will be upgrading network infrastructure.

Customer Impact: During the previously scheduled maintenance on April 20, the network provider experienced issues moving some data connections to new network infrastructure. As such, the maintenance was not completed. To complete that work, on Friday night, May 4, an upstream network provider will be moving multiple data connections that may affect ImageSilo to new equipment as part of a major network overhaul. After the move is completed, ImageSilo engineers will work with the provider to ensure that all primary and redundant paths are fully operational. No customer impact is expected, however, due to the nature of the issues experienced on April 20, and out of an abundance of caution, we would recommend planning for up to an hour of interruption on Friday night.

Questions/Comments: Please feel free to contact ImageSilo Administration with any questions or comments.

ImageSilo Service Bulletin Update

This Service Bulletin Update is in regards to the Emergency Maintenance that was declared earlier this morning. ImageSilo engineers have identified the root cause of the extreme system performance issues experienced this morning. The issue lies in a bug in the load-balancers that handle traffic for ImageSilo. In this bug, the on-board SSL (encryption/decryption) offloading card can stop working properly, resulting in the extremely slow performance we experienced this morning. Engineers took steps necessary to temporarily address the bug and full performance was restored by approximately 10:17 AM (MST). During this weekend’s previously scheduled maintenance, ImageSilo engineers will take steps to permanently address the bug.

We apologize for any inconvenience this performance degradation may have caused. As always, we sincerely appreciate your business.

ImageSilo Emergency Maintenance Notification – Jan. 20, 2012

Start Date: January 20, 2012 (Friday)
Start Time: 10:06 (MST)
Finish Date/Time: Not yet determined

Purpose: ImageSilo engineers are investigating a performance issue that is causing extremely sluggish performance of the ImageSilo system.

Customer Impact: At this time, the issue appears to be specifically limited to SSL traffic (not the web or application servers themselves). We are engaging vendors to assist in troubleshooting and addressing the problem. We anticipate failing over firewalls and load-balancers as part of those troubleshooting steps. Customer impact will be unknown. We will post another update as more information becomes available.

Questions/Comments: Please feel free to contact ImageSilo Administration with any questions or comments.

ImageSilo Maintenance Notification – Jan. 20, 2012

Start Date: January 20, 2012 (Friday)
Start Time: 20:00 (MST)
Finish Date: January 23, 2012 (Monday)
Finish Time: 04:00 (MST)

Purpose: Apply security updates and patches to multiple ImageSilo systems.

Customer Impact: ImageSilo engineers will be applying security updates and patches to a number of ImageSilo systems. Expected impact is approximately four periods of high latency (up to two minutes each) as domain authentication fails over to redundant hosts, a few FTP session interruptions (which should automatically re-connect if using Data Transfer Manager), and two periods of limited access/interruption (up to five minutes each) for database fail-overs.

Questions/Comments: Please feel free to contact ImageSilo Administration with any questions or comments.
