Reboot SFX Server (Sunday, July 9th)

Wednesday, July 5, 2017 - 3:05pm

This Sunday, July 9th between 8AM and 10AM, I will reboot the Production sfx.carli.illinois.edu server. Downtime should be less than 5 minutes.

I am doing some Apache HTTPS work on the server and some of the settings cannot be enabled until I restart this service.

Wednesday, June 21, 2017 - 11:17am

Production CARLI servers will be patched this Sunday, June 25th between 6AM and 10AM.

This work requires a server reboot and it takes a while for Oracle and Voyager to shutdown and start back up. Downtime should be no more than a half-hour.

Network Outage Today (April 28)

Friday, April 28, 2017 - 4:05pm

I apologize for the service outage this afternoon. I was making network changes and created a route loop that caused our primary and secondary networks to go into a disabled state. This outage took longer than normal to resolve because I needed to contact campus networking staff to bring the disabled ports back online.

I obviously need to make some changes to our network plans. There are two changes I can think of right now:

1) I will look into making changes to our network to make sure I can immediately enable any ports that go offline.

2) I will move this work to Sunday mornings until we are confident it will not cause outages.

Again, I apologize for this disruption to your institutions.

An updated server used behind-the-scenes with VuFind 0.6 and VuFind 3.x will be put in place between 6AM and 10AM on Sunday, April 9th. The outage should be less than 20 minutes if everything works as expected. If not, we may remove the new server and put the older one back in place.

Dropping Network Connections

Wednesday, March 15, 2017 - 3:15pm

This afternoon I was doing maintenance on redundant security devices. The devices are supposed to preserve network connections when one device in the pair is restarted, but I have learned that we are dropping those connections.

I am holding off on further maintenance until later tonight. I will also investigate why connections are not being preserved. I apologize for kicking you off of our servers twice this afternoon.

At around 11:42AM today (Friday, Feb 24) the UIUC campus lost their network connection between the Internet and their firewalls.

Network Firmware Upgrades this Sunday, Jan 15

Thursday, January 12, 2017 - 8:18am

This Sunday, January 15 starting at 6:30AM, campus networking staff will be upgrading the firmware on a large number of network devices. This includes the devices in our Production Data Center. Since we have redundant routers and switches, I am not expecting any downtime during this work but I wanted to make you aware of it just in case.
