One of the redundant uplinks to our Brisbane VPSs has been flapping. We are working to resolve this with our upstream.

All traffic is currently pathed over the redundant pair, no impact is expected at this time.

We have been advised that our upstream provider in Dallas is adding an additional 20G of network connectivity to their network.

Start Time: 03/29/2020 12:00 AM (CDT)
End Time: 03/29/2020 2:00 AM (CDT)

They do not expect any service degradation during this maintenance window.

To see if you have the issue run: netstat -ntpl | grep 8009 and it will list the process listening on that port.  Check if it is bound to the public IP address (vs. a localhost IP address).

To mitigate the issue add an address="127.0.0.1" attribute to the Tomcat Connector for port 8009.

If you have Tomcat in /usr/local/tomcat; then edit /usr/local/tomcat/conf/server.xml

Change:
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

To:

<Connector port="8009" address="127.0.0.1" protocol="AJP/1.3" redirectPort="8443" />

Then restart tomcat; e.g. with /etc/init.d/tomcat restart

Then re-check the ports that you have open and make sure port 8009 is only available from the local IP.  e.g.
# netstat -ntpl | grep 8009
tcp6 0 0 127.0.0.1:8009 :::* LISTEN 11615/java

If you need our assistance resolving this issue, please just reply to the email we have likely already sent you on this issue.  Should we need to log into the server, please ensure we have access there per https://rimuhosting.com/knowledgebase/rimuhosting/rimuhosting-ssh-access else we would need to restart your server in order to enable our access.

We are seeing packet loss via some routes in Dallas.

We are investigating.

Update Sun, 22 Mar 2020 20:03 PM UTC: This affected some customers via Cogent routes. We are no longer seeing an issue.

Update Sun, 22 Mar 2020 22:10 PM UTC: The issue has been resolved.

MAINTENANCE WINDOW START : 2020-03-25 - 1:00AM AEDT https://www.timeanddate.com/worldclock/fixedtime.html?iso=20200324T1400
MAINTENANCE WINDOW CLOSE : 2020-03-25 - 6:00AM AEDT

During this window our upstream provider will be performing maintenance on our primary circuit.

Traffic will be moved to our secondary circuit before the maintenance starts, and moved back once it has been completed. No impact is expected.
