Indianapolis BDII (is2.grid.iu.edu) Instability

Data instability was seen today in the Indianapolis-based BDII (is2.grid.iu.edu) between the hours of 18:30 UTC and 21:45 UTC. During this time availability of OSG Sites Data was inconsistent.

The problem was traced back to a IP renumbering project which had unforeseen affects on our internal DNS and LDAP. As soon as the issue was identified, the maintenance was stopped and service was rolled back to the pre-maintenance configuration.
