Thanks for the reply - we aren’t directly using the drop feature, we are building with GatsbyJS.com - its linked to Netlify via an ‘Integration’ and it automatically deploys to Netlify, perhaps it does use this feature - but we do need to get it reliable if possible.
Since cancelling all the stuck deploys most now deploy ok, some get stuck.
The website is for a degree show for the Royal College of Art in the UK - its a big project (up to 1000 students uploading up to 100 files each, not all students are going to participate and most far fewer - also we’re using gatsby to optimise all the images). However its definitely a big site.
For now we are using a regular webhook request on gatsby to enable incremental builds and have the site building every 30 minutes while students upload so they can see a preview. The results are here: https://app.netlify.com/sites/rcapreview/deploys and its been working very well for a few hours - you can see a few failed deploys, these are where it got stuck and I cancelled them.
We will probably be using this site for the live version: https://app.netlify.com/sites/rca2020/overview and will be switching this to the live subdomain next week. Can you let us know whether using Netlify Enterprise will be necessary, we are strongly considering it, its primarily the support we wanted to do this for, but its vital that its reliable.
all the best
