Affects: Traffic hosting

At 22:40 CET, 1 Februari 2019 we have noticed a linecard crash on Router 1 of the datacenter Databarn Amsterdam.

As the linecard restored quickly after the crash there might have been interruptions of services due to the failover process.

We have made dumps of the crash logs and provided the information to the vendor for further investigation while we continue to monitor stability of the linecard.

Update 2019-02-02 8:35 CET:
We experienced another linecard crash at 2019-02-01 22:45 CET, which may briefly (~ 2 minutes) caused packetloss on your services in DBA.

Update 2019-02-07 12:46 CET:
We experienced another linecard crash last night at 3:13 AM CET, which may briefly (~ 2 minutes) caused packetloss on your services in DBA, this crashdump was added to the case with our vendor.

Update 2019-02-13 8:03 CET:
Around 18:28 CET, 12 Februari 2019, we have found our other linecard of our DBA router has crashed. We have submitted crashdump as well as other dumps to provide as much information as we can.

Update 2019-02-16 06:35 CET:
We experienced a linecard crash of both linecards in R1 and R2 of DBA. where also the BGP with our transits was dropped which needed to be re-converged after coming back online, this may have caused packetloss or unreachabillity.

Update 2019-02-18 04:52 CET:
We experienced linecard crashes both on R1 and R2 of DBC. As the stacktraces are exactly the same as the crashes of DBA, we expect this to be the same issue. Currently the vendor is still investigating the debugs.

Update 2019-04-18 14:00 CEST:
We have received an update from the vendor, having the issue found and solved. A new firmware will be released including the fix.
Once we have received the firmware, we will begin planning in firmware upgrades.
