Updates broke my OWA

After applying the latest round of updates, with the exception of one (IE 10 Update) none of my mobile devices or my OWA page is working. It's as if all the web services have been turned off. However, everything else is working.

I've check both internal and external urls and the error message is the same "Web page not available. Error 103 (net::ERR_CONNECTION_ABORTED): Unknown error."

Any ideas would be greatly appreciated

All services are running for exchange, www and IIS.
Can you check and list the updates you just installed?

One of them is making this issue, try to findout and uninstall that update. Everything will be good after that.

Check updates detail and findout related one (related to IIS and exchange)
Thanks for that, I will check and reboot the servers if required tonight and let you know tomorrow morning.
Which Exchange specific updates were installed?  You can view that by checking the Updates History on the Windows Update page.

Rollup6 for SP2 broke my web services.. but the fix was as easy as running the updatecas.ps1 script in your exchange server working directory.
Try running the UpdateCAS.PS1 on the CAS server and then check
