Post dealing with changes to how we route packets and configure our network.

Unexpected Reboot

UPDATE Two:
Combing through the physical host logs and reading things line by
line turns out a set of errors that might be concerning to our
operations, but we aren’t sure just yet.

We are continuing to check on the machine and watching for problems
that may be affecting us.

UPDATE One:
We got in touch with the data center and they are saying
“As these are unmanaged servers, we do not actively monitor
customer services, so we do not know when or why a services
goes offline.” Which we understand, the operation of the
hardware is on us, but this is something outside of our
project from the looks of it.

Our team will continue to work on restoring network services
and will monitor the system for the next few hours to see
if any issues arise.

We got some alarms sent to our team around 1214EST this
afternoon that large portions of our network went offline
without warning. Upon logging into our management consoles
and looking things over, it seems that our physical host
“Adrian” rebooted.

We have reached out to the data center to see what may have
happened and our team is in the process of restoring our
network functionality.

PTR Records Updated

Our team noticed that a handful of our PTR records were
incorrectly set and some of them were doubled up for
different host, which comes from the old v2 network
layout. The important routing PTR entries have been
updated to match the current network, v3.
