Analysis of Network Outage Reports Cybersecurity and Communications Reliability Division – Public Safety & Homeland Security Bureau John Healy August 2016

Frequency of Outages by Month

Standards for Outage Frequencies Took average of January 2013 through December 2013 as the standard For Planned Maintenance Took average of January 2014 through December 2014 as the standard

Frequency of Outages by Month 1.2%

Outage Index – For All Outages Except DS3-Simplex See ATIS-0100021 Analysis of FCC-Reportable Service Outage Data for a description of the method used to calculate the outage index.

New Planned Maintenance Cause Codes

New Planned Maintenance Cause Codes 2.1%

DS3 (Non-Simplex) Events

DS3 (Non-Simplex) Events 2.0%

Big DS3 Outages

DS3-Simplex

DS3-Simplex 0.8%

Fiber Cut

Fiber Cut 0.7%

E911

Very Large E911 Outages

E911 – Phase 2 Events

E911 – Phase 2 Events

Wireline Wireline outages are all outages for which the Reason Reportable was at least 900,000 wireline user-minutes.

Wireline -0.9% Wireline outages are all outages for which the Reason Reportable was at least 900,000 wireline user-minutes.

Wireless

Malicious Events

Malicious Events

Malicious Activity The figures for 2016 are thru June.

Duration Trends: DS3 Non-Simplex The duration of DS3 non-simplex outages is statistically unchanged in 2016 compared with 2015 (using a Mann-Whitney test). 11

Duration Trends: E911 The duration of E911 outages is statistically unchanged in 2016 compared with 2015 (using a Mann-Whitney test). 6

Duration Trends: Wireline The duration of wireline outages increased from 2015 to 2016 (statistically significant using a Mann-Whitney test). 119 96

Duration Trends: Wireless The duration of wireless outages is statistically unchanged from 2015 to 2016 (using a Mann-Whitney test). 12

Duration Trends: DS3 Simplex The duration of DS3 simplex outages is statistically unchanged from 2015 to 2016 (using a Mann-Whitney test). 226

Duration Trends: Other Special Facilities The duration of other special facilities outages decreased from 2015 to 2016 (statistically significant using a Mann-Whitney test). 12 5

Duration Trends: VoIP The duration of VoIP outages increased from 2015 to 2016 (statistically significant using a Mann-Whitney test). 9 12

Test for Trend in Event Duration Non-DS3-Simplex Outages Data from 1/14 thru 6/16 DS3-Simplex Events Only Data from 1/14 thru 6/16 Rank Correlation of duration with date is -.012 and is significant at the .02 level Rank Correlation of duration with date is -.013 and is not significant at the .05 level Conclusion: Non DS3-Simplex Outages are shorter in duration from 1/14 to 6/16 Conclusion: DS3-Simplex Events are unchanged in duration from 1/14 to 6/16

NORS Transition NORS coordinators began to test the new system in April June 2 - Training session on the new NORS August 29 – Public Notice on new NORS is published August 31 – CenturyLink, T-Mobile and Verizon cutover to new platform September – Remaining companies cutover to new platform

NRSC Activities Current Teams Best Practices Team Outage Reporting Advisory Team Improvements to the NORS System Improvements to the template Recommended ways to communicate information Improvements to NORS/DIRS manuals IP Transition Team Consistent Use of Cause Codes
