For anyone that reads this, I am working through an OMITT SSL issue with @Pepe LeFrits. He's off in Central America without his laptop, the lucky devil.
In theory the SSL certificate for OMITT might expire at some stage in the next day or so, which might either lead to SSL errors accessing the site, or to an outage until a valid renewed certificate is installed.
That is a routine fix but nothing you can do on your phone easily, so at the minute I'm waiting on Pepe to give me access to the service we use to get our free SSL certs.
If you do get SSL cert errors on OMITT in the next day or two, you can be more confident than usual it's because the site administration got screwed up and not because anyone's trying to MITM your browsing. Happy days 👍️
