I know this is an old topic, but a few days ago I noticed that I can't load mempool.space with Tor or VPN, while with a regular IP address I don't have those problems. Can anyone check if they have the same problem?
On mobile or desktop? Because I often had similar expereince loading mempool on my mobile with no VPN just on chrome, it will keep loading and I have to refresh the tab or force close it then opening it after a while will work fine but on desktop clearnet I never had any issues.
I can't remember when I last tried to load it on my desktop, but on my mobile phone, yes, I often tried, and for the last couple of months, if not a year (I can't remember the actual time it started), it's unusually very slow. I mean, it could struggle for many minutes before it loaded. I believe the problem is resident, and using a slow connection will aggravate it. That's why @Lucius's Tor or VPN connection could struggle more because the connection he was routed to could be slow.
Along the line, out of curiosity, I abandoned mempool.space and discovered mempool.emzy.de. It has been flawless in loading.
