Purpose: Investigate BGP/routing issues.

Customer Impact: ImageSilo engineers, in coordination with upstream network providers, is investigating unexpected BGP advertisements that appear to be taking ImageSilo network traffic through suboptimal routes. If BGP advertisements are adjusted, a brief period (i.e. less than 30 seconds) of higher than normal latency may be experienced while traffic re-converges.

Purpose: Replace failed hardware in storage systems.

Customer Impact: ImageSilo engineers will be replacing a failed IOM on a storage tray attached to one of ImageSilo’s storage systems this evening. As the systems are fully redundant, no customer impact is expected.

Purpose: An upstream network provider will be replacing failed hardware in a core router.

Customer Impact: Network provider engineers will be changing OSPF metrics before and after the hardware replacement to force traffic to redundant links. During these changes customers are expected to experience latency or traffic interruption for up to 10 seconds.

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.

Purpose: An upstream network provider must depeer a redundant ISP connection on a local internet router to reduce the service effect of carrier vendor maintenance.

Customer Impact: Some customers may experience minor latency while traffic converges during the maintenance period.

Purpose: Identify and resolve database performance issues.

Customer Impact: ImageSilo engineers are investigating performance issues with the ImageSilo databases. Software vendors have been engaged and hardware vendors will be engaged as necessary. Engineers may take steps to resolve the issue that cause temporary interuption of ImageSilo services. An update will be posted once the issue has been resolved.

Purpose: Upgrade switching infrastructure firmware.

Customer Impact: Through working with the equipment vendor to address yesterday’s Emergency Maintenance relating to network switching, it was determined that an updated firmware version may offer fixes that address issues that were manifested in the port flapping and spanning tree incidents. As such, ImageSilo Engineering has determined that the most prudent course of action would be to perform these upgrades as soon as reasonably possible. The upgrade has been performed in a lab environment and tests indicate that the upgrade takes takes about 8 minutes for the switches to fully restart as this is upgrade is not a rolling (non-disruptive) upgrade. Engineers will be performing the upgrade at the Kansas City facility during the day tomorrow (these systems are backup systems, not customer facing or impacting) and will then perform the upgrade at the primary facility in Denver tomorrow evening. The upgrade at the primary facility is expected to cause approximately 8 to 10 minutes of service interuption while the switching equipment fully reboots.
