See news links posted below. I (and thousands other people) have been unable to use a browser normally in our mobile phones for the past week. Since Apple forces everyone to use the same underlying webkit engine, all browsers are broken. It's quite frustrating to have your 800€ device unable to perform one of it's basic duties.
That a particular website can completely break the ability to open links in all applications on all websites just by listing too many URLs in a file, with the broken state persisting even after the original website fixed the file that caused it, is definitely Safari's fault.
The news he is referring to is that many developers improperly coded their app in regards to misusing universal links. Bookings.com already fixed the issue on their end so you can simply reinstall it. Apple is also working on a fix to handle apps that haven't fixed their issue yet: http://9to5mac.com/2016/03/29/apple-ios-9-crashing-bugs-when...
