December 4, 2014 - Intermittent and brief periods of traffic latency at North America 1 Datacenter

Post 11:00 AM CST, December 4

This morning, our North America 1 datacenter experienced two brief periods of traffic latency.  Each one has lasted between 10-15 minutes. The first one occurred shortly after midnight CST. The second one at approximately 10:00 AM CST. The Internet Health Report has shown this latency on the routes connecting with Chicago and impacting the connection by and between Savvis (a division of Century Link) and Level 3 — both regional backbone providers.
Currently, our internal monitoring indicates that this latency may be associated with brief traffic spikes on the regional net. We are working with our backbone fiber providers and local datacenter management to further identify these spikes.
The latency periods have been brief and self-correcting by our redundant network. No internal sites or services are impacted and the traffic does not currently have the characteristics of a conventional attack, DDoS or otherwise.
The Infrastructure Team is actively investigating this issue. As we learn more, updates will be posted to this news item. 

Final Update, 3:30 PM CST, December 5 

A thorough review has been completed by our internal Infrastructure Team, and final incident reports have been issued to us by our datacenter and connectivity providers.  This end-to-end evaluation showed no internal issue or causation.  It has been concluded that the regional connection issue reported by Internet Health Report during the incident is the sole, likely root cause of any latency experienced and was resolved by automated fail-over network rerouting.
Again, the issue was limited to two brief occurrences, each lasting between 10 and 15 minutes on December 4th as described above.  If customer experience any issue inconsistent with this information they should contact the support team for immediate assistance.
