Passport Database Outage Leaves Thousands Stranded
linuxwrangler (582055) writes Job interviews missed, work and wedding plans disrupted, children unable to fly home with their adoptive parents. All this disruption is due to a outage involving the passport and visa processing database at the U.S. State Department. The problems have been ongoing since July 19 and the best estimate for repair is "soon."
The system "crashed shortly after maintenance."
Rollback plan? What is that?
Sic the healthcare.gov guys on it. I'm sure it'll be right as rain in no time.
From their Q&A:
Q: Why wasn’t there a back-up server?
Back-up capability and redundancy are built into the system. The upgrade affected our current processing capability, in part because it interfered with the smooth interoperability of redundant nodes.
We don't need backups, the data is replicated, we're cool.
I'm sure they have full copies of all the data already.
The article tries to wow us with the hugeness of the database, like this is a reason for the issues.
Yet the numbers quoted are not that big. Any modern PC isn't going to get too upset handling 75 million things. A real data center is going to sit there wondering what to do with the remaining 500TB of storage.
I don't doubt that there is some horrible flaw in the way the system was conceived that rendered it fragile, but whatever it is, it's nothing to do with the enormity of the problem, because it isn't very enormous.
I should use this sig to advertise my book ISBN-13 : 978-1501515132.
Or worse, they're running SQLServer on Sun boxes...
