Public wifi menace

A couple of days ago, I was looking up a bus timetable from my ‘phone.  All perfectly mundane.

The address I thought I wanted failed: I don’t have it bookmarked and I’ve probably misremembered.  So I googled.

Google failed too.  With a message about an invalid certificate.  WTF?  Google annoyingly[1] use https, and I got a message about an invalid certificate.    Who is sitting in the middle?  Surely they can’t really be eavesdropping: with browsers issuing strong warnings, they’re never going to catch anything sensitive.  Must be just a hopelessly misconfigured network.

I don’t care if someone watches as I look up a bus time, I just want to get on with it!  But it’s not obvious with android how I can override that warning and access google.  Or even an imposter: if they don’t give me the link I wanted from google, nothing lost!

So has my mobile network screwed up horribly?  Cursing at the hassle, I go into settings and see it’s picked up a wifi network.  BT’s public stuff: OpenZone, or something like that (from memory).  This is BT, or someone on their network, playing sillybuggers.  Just turn wifi off and all works well again as the phone reverts to my network.

Except, now I have to remember to re-enable wifi before doing anything a bit data-intensive, like letting the ‘phone update itself, or joining a video conference.  All too easy to forget.

Hmm, come to think of it, that broken network is probably also what got between me and the bus timetable in the first place.  That wasn’t https.

[1] There are good reasons to encrypt, but search is rarely one of them.  Good that google enables it (at least if you trust google more than $random-shady-bod), but it’s a pain that they enforce it.
