Better to use a service like this than anectdotal reports from other users:
https://www.isitdownrightnow.com/
it’s down.
apparently they moved to a new platform yesterday:
https://reclaimthenet.org/new-gab-decentralized-version/
I get the main page at gab.com to load but my account does not show up, just a new registration page. Gab.com is down according to three site trackers.
I’d be a little cautious about the possibility of fake or phishing sites as Gab would be an ideal target for hackers.
