Dtube is having temportary problems with their upload servers. They should get it under control. You can also join the offical dtube discord here, @nannal does a great job with the tools he has. https://discord.gg/GxmW9pJ

Us fans of dtube in One Love, we made a discord bot to decentralize videos into different locations through discord itself. It's free for standard def content you can use it if you like. We have paid plan for HD Stuff, similar to google drive. It's currently in the one love dtube and Helpie discord.

showcased here. i backed up your last video. you can notice now , how it loads really quickly compared to the others.
Another thing. steemit.com just doesn't work for me anymore. I'm using steempeak.com.
Have a great day, i enjoy the shit outta your dtube content and will continue to try to improve our "community hosting solutions" to better both our content creators in one love / helpie and those like yourself who have been instrumental in supporting dtube from the beginning. We see you working and we appreciate it.
