Why Your arXiv Submission is Stuck: A Deep Dive into Delay Times

Frustrated by my arXiv submission being stuck on hold, I analyzed over 60,000 papers from 2015 to 2026 to find the cause. While overall delays haven't increased, I discovered that specific categories like cs.CY and physics.pop-ph face significantly longer waits, likely due to reclassification needs. This data reveals that your submission time depends heavily on your chosen subject category.

So if you're submitting to a new arXiv subject, don't rely on the time to announcement being the same as you're used to.

    Just wanted to say that the plots are so nice. They perfectly balance visual noise and information density, _and_ they're aesthetically pleasing.

    Yes, the daly time recently is absolutely ridiculous. Been waiting on a preprint that's already been accepted in a top journal for seemingly no reason.

    I'd like to see a cumulative version of that power law plot. How many papers had a delay of at least X days.

    I have been bit by several inexplicable, long delays recently. In my case, I suspected the reason was choosing stat.ml as primary and cs.lg as cross-list, which, after my time in purgatory, was flipped (without asking me, of course). My choice was completely defensible.

    It's almost like peer review all over again!
