Oops! We had a minor SSL certificate issue which is now fixed. Apologies for any inconvenience.

EXCITING TIMES! We have upgraded to Mastodon v3.0.0.


Thanks to @Gargron and all the development team for their hard work 🙂

HI EVERYONE. Mastodon v3.0.0rc1 has just been released and we've updated the instance already.


We've just carried out an essential infrastructure update. You might have experience a very brief outage this morning but everything's up and running again.

Hi folks, we’re investigating reports of performance issues. We’ve restarted the Mastodon service just in case.

We experienced what appears to be a DDoS attack last night. This was all handled by flow control upstream on our network and as far as I can tell this didn't cause any downtime.

We've suspended the weedis.life instance due to a flood of spam follows from dozens (hundreds?) of random users. A temporary suspension for now but we'll keep an eye on it.

If you are using Toot! or Mast on iOS please do consider leaving them positive reviews to counter-act trolls!

Do you have any suggestions for mas.to? Good or bad feedback? Let us know! 🙂

It’s been brought to our attention that our SSL certificate hadn’t renewed automatically as it was supposed to. This has been fixed. Apologies for any confusion or inconvenience this caused.


It's Mastodon v2.9.1, and it's installed on this instance.


Do you use keybase.io? Then you can prove your mas.to identity! In your keybase.io profile, select ‘prove more identities’ and then pick ‘mas.to’ from the list.

MORE UPDATES. Everyone likes updates! We've just updated to v2.9.0.

We're proud to embrace the Mastodon Server Covenant and are now listed in the joinmastodon.org instance finder.

Hello! This is mas.to, a general-purpose, predominantly English-speaking instance. We're enthusiastic about Mastodon, and want to make this instance special. We've settled on a nice, short domain name, keep up-to-date with the latest Mastodon updates and features and want to make an easygoing and fun place to interact with other Mastodon users.
