The DSS-27 problem started on DOY 319 and was resolved on DOY 321. IMPACT: The SSR playback was up-to-date before the SSR failover. Only a 31 second data gap during the SSR failover on DOY 321 (10:16:02-10:16:32). The following pass (DOY 321) was extended to 5 hours 25 minutes to dump the full SSR. Note, the reported data capture statistics cover Sunday-Sunday. The 31 second data gap will be reported in next week's data capture statistics.
