Reliability and Availability
I have yet to see the platform down or running slowly, but there have been multiple instances recently (Q2 2015) when the user links to a news story and Owler gives an Oops message. Users simply click on the story a second time and the story is displayed. This is a nuisance bug.
I also have a sense that the system is not processing alerts as quickly as before, but I haven't tracked this closely, so I could be wrong about it.
