The peering points for IT Sligo's General IP service will be migrated to
the two new CRS routers in Citywest and Kilcarbery Park.
No service interruption is expected. Commissioning and testing will involve
BGP sessions being established and torn down, which may result in periods
of asymmetrical routing while BGP converges.
20080404 16:50 LT Opening ticket to track work.
20080408 09:13 LT IT Sligo now migrated to new network via two new BGP
sessions (old BGP sessions still in place for failover but these will be
removed over the next while). Some of the testing ran beyond the scheduled
period so there was a period of a few seconds at approx 09h05 when BGP was
converging and ability to route packets to and from IT Sligo was impaired.
Will monitor the new sessions for 24 hours.
Time to Fix:
Actual outage of a few seconds.
