There's a post on Reddit that confirms the outage. The major problem here is their status page that says everything is fine after about an hour and a half of outage.
Glad to know I'm not alone. Also, Proton's offering to be a replacement to the big wigs - as it turns out even the little people need their emails and calendar. I was kind of scrambling to think of what I could do as a work around and pretty much settled on I've got nothing.
Their systems currently report that everything's fine, which - to be fair - could be a misreporting and change at any moment Anecdotally all their landing sites load fine for me
Tackling it from the other side: could it be a problem with your DNS? Did you try with another network? Like wifi or mobile data
EDIT: Formatting
EDIT: Tried again and now the email service seems to not be loading
It's pretty unacceptable its been down for several hours and their status page says all is good. I get shit happens, but the lack of transparency is making me reconsider paying for service next year.
I'm also having issues, today with proton VPN I've been having major delays, I tried hotspotting from my phone and three other WiFi connections and it wasn't until about 20 minutes of trying, changing servers, that I finally got a slow connection. Also my phone internet seemed to be crawling.
