We'll have to replace the NIC in nlsh04 due to instability issues. This will be done likely Friday or Saturday.
Update 28/Mar 9.21pm: We will replace the NIC tomorrow evening (sunday) around 10pm. This will result in a bit of downtime, since we have to power off the system, remove it from the rack, to switch out the hardware, rack it and turn it on again. After this we have to adjust network configs. We'll do our best to keep the downtime as short as possible.
Update 29/Mar 8.18pm: We'll start the hardware replacement slightly after 10pm. We'll initially prepare new configs and the parts so we keep the downtime as low as possible.
Update 29/Mar 10.23pm: We'll shut down the server in roughly 10 minutes.
Update 29/Mar 22.50pm: The system is back online again, total downtime for IPv4 was 12 minutes and 7 seconds. IPv6 being 14 minutes and 9 seconds. We'll monitor the situation for a bit, before we leave the datacenter.
