Here's a quote from a Register article, which leads to some obvious conclusions:
However, within the comments of the BA chief executive there is one telling statement:
Tens of millions of messages every day that are shared across 200 systems across the BA network and it actually affected all of those systems across the network.
Sorry for the text speak, but WTF? How does it require 200 systems to issue a boarding pass, check someone in and pass their security details on to the US – even if they aren't going there? Buried deep in
The Register comments on the article is an allegedly former BA employee claiming that this is in fact the case, that all of these systems are required for BA to function. How did BA get to the point that there are 200 systems in the critical path?
