SDLN problems Monday Aug. 31

We are once again experiencing a power outage with an unknown cause. We're currently taking all possible measures to insure Aleph remains running for the longest time possible on our UPS. Once we know more information we'll let everyone know.

Do you Twitter?

We plan to post information about new resources, scheduled and unscheduled downtime, and much more.

A bit of information about Friday's system downtime.

From Warren Wilson at SDLN:

To share more information. There were numerous problems last Friday. The first power related problem was with a substation that the University shares with part of the city. This problem was fixed relatively quickly. Then the crews started working on the substation that feeds the campus. All three breakers had blown and they had to get new breakers from Rapid City. As they narrowed the search down, it was a bad transformer to one of the building, actually the Young Center, the athletic building. They had to bypass that bad transformer. When power was restored to campus. The Library’s power did not come backup. The main switch/breaker for the building is bad and they had to force a connection to get power restored to the building. At some point, we will schedule another outage so that we can get that switch rebuilt.



The SDLN UPS worked great. However, all of the network connectivity off campus lost power. So until power was reliably restored, the network connection did not come back up. I am in conversations about how this can be brought over to the SDLN UPS. I will keep you posted.



If you have any questions, please let me know.

At this point in time, a temporary fix has been implemented to restore power to the library building. All SDLN resources should be accessible again including Aleph and OPAC. Once we have news on a more permanent power fix we will make sure to send out an announcement. Our UPS has been charging so in the event of another shorter power-outage, our systems should continue to run for a while again.



Thanks,
Sean

We are still without power and our UPS is just about out of power. There is an issue at one of the power companies substations that supplies power to the campus of BH. They are currently working on the issue but at this time they do not have an ETA on the solution. In about 10 minutes we will be forced to shut down Aleph before it shuts down incorrectly. Once we have an update, and if we’re able to, we will send out another update message.



Thanks,

Sean

We are currently experiencing a campus wide power outage. SDLN is currently running on our UPS and that will keep our servers on for about an hour. However the campus internet connection will likely lose power shortly and all services will be off line until further notice. Sorry for any inconvenience if you have any questions feel free to contact us. Thank you
