Updated 3:45 p.m. to reflect network back online.

The website for the Ann Arbor District Library was down because of a problem with its fiber network, according to a message sent out on the AADL Twitter account. "We're working on it! stay tuned and thanks for your patience" was the Monday 11 a.m. message; by 3:45 p.m., the web site reported and we're back!

Due to the construction next door, the fiber that connects the downtown library to our branches and to the internet (via the glass cabinet on the 2nd floor of the Ann Arbor Hands-on Museum) needed to be rerouted to avoid the upcoming excavation. What was supposed to be a 15-minute splice actually took the contractor 5 hours to troubleshoot, but we're back up now! Thanks very much for your patience, and please contact us if you have any other questions or trouble.

The outage affected other sites hosted inside the Ann Arbor District Library network, including Arborwiki, as well as internet access from library branches.
