Just downloaded my Twitter archive again and converted it to Markdown, including high-res images this time. I suggest you do the same if you want a backup of your data that is independent of Twitter’s servers and free from obfuscated t.co links.

Here’s a quick how-to:

@matthiasott I requested my archive 3 days ago and haven't got it yet. Not confident it's coming. 😬
@AshleyMarineP @matthiasott same here… just requested again but wouldn’t it be convenient if they disabled this whole feature?
@yuletide @AshleyMarineP @matthiasott they can’t at least in the EU as it is a law requirement
@enkydu @yuletide @matthiasott They've already broken so many laws with the layoffs here, it wouldn't surprise me.
@matthiasott @AshleyMarineP @enkydu finally got it yesterday
@yuletide @matthiasott @AshleyMarineP I think it depends on size of archive. I request my archive this week and I received link for download next day. But it was only 70MB. I know about people with 3-4GB archives.
@AshleyMarineP @matthiasott @enkydu mine was 120mb and took about 3 hours to generate before #elongate so I’m guessing this is a resource issue
