When a website leads you to a blank 404 page, the question isn't whether it's safe to use — it's whether there's anything to use at all. axonstorage-dpoxu68jm2gc.edgeone.app is a subdomain that currently shows nothing but an error. For any legitimate business or service, a functioning homepage is the absolute minimum. This one doesn't even have that.
Without a working site, we can't verify who owns it, what they offer, or how they handle your data. Most personal blogs and hobby projects don't need extensive legal pages, but they typically do have at least a few sentences explaining what the site is about. Here, even that is missing.
If you're wondering is axonstorage-dpoxu68jm2gc.edgeone.app a scam, the honest answer is that the evidence is too thin to call it a scam, but it's also too thin to call it legitimate. There is simply not enough signal to assess. Our recommendation: wait until the site actually loads and provides meaningful information before considering any interaction.
