I don't see an announcement about this on the main web site, so I'll drop a short note here....
The University of Michigan Plant Operations department is performing some electrical work in our machine room starting at 8am this morning. The work will last some unknown number of hours; my guess is 4-6.
We have just diverted traffic from our production web site over to the replica in the cloud. Our most common services such as search, download, and on-line analysis will be available. But services which require our web site to "remember" something -- such as data deposit, Summer Program registration -- are not enabled in the replica.
I'll post a follow-up once the work has completed, and will check back here periodically for comments. If you see something that isn't working as you think it should, please comment here, and we'll take a look.
10:22am EDT : We're aware that study search is not working. (Variable search and bibliography search are working.) ICPSR recently updated the search to include the full-text of many types of documents (codebooks, survey instruments, user guides, etc), and the index location changed too. This change was not reflected on the cloud replica, and the index there is now building. Our apologies for the inconvenience this may cause.
ETA for conclusion of the electrical work is between 11am and noon EDT.
11:18am EDT: The power work has been completed. We've restored service to the main site.
