Open Hub Scheduled Downtime

There are two periods of scheduled downtime for the Open Hub over the next week or so.

The first will start tomorrow, Friday, April 28, when Black Duck’s IT team starts a network update project in our production data center. There may be a series of service interruptions through this weekend. We do not expect that the Open Hub will be down for any long period of time should it be unavailable, although these service interruptions will be unpredictable.

The other service interruption will start on Friday, May 5 at 8 PM EDT. We will be taking the Open Hub offline at this time in order to perform a significant architecture upgrade. Unfortunately, this work cannot be done during the IT work window because the network upgrade will mean, by definition, that the network and some systems will be unavailable.

We’re really excited by this architecture upgrade, which we’re calling the FIS – OH Database Split (FODS) project. ┬áThis work is separating our back end that provides the Fetch, Import, and SLOC operations from the Analysis and UI operations. This is the culmination of a significant amount of work over more than a year as we took incremental steps to mitigate production risk, expand our capabilities and scalability, and improve our website performance. To do this, we need to pull the site offline to make a backup, restore it to two systems, and then run a series of scripts to update the schemas for the new two database architecture, then all the applications need to be deployed and verified before we bring the entire set of systems back online. We expect that all this work will take the majority of the weekend and the Open Hub will be unavailable throughout this work.

As always, thank you so very much for being a member of the Open Source Software community and a part of the Open Hub.
