I realised on Tuesday 22nd Jan 2019 that my Ghost Blog host had just given up. Their portal still worked, but pictures were not loading, they were not responding to emails and my blog was returning http 503 for over 24hours.
Ghost has an export feature, but I couldn't get to my blog to export it. Luckily Google had all my pages cached, but some without images. At least I can republish them!
Don't trust 3rd parties - do backups yourself even if they are too
Write blogs in a local editor before publishing to the web
Store images yourself
Hopefully I'll have the blog fully operational by the end of the week - Fri 25th Jan 2019
