Our services

This page gives an overview of the services we host. We give some information regarding the support status and privacy of each service.

Nextcloud ↗

Wiki

Store your files, calendar, contacts and many other things in the pub.solar cloud. Access from all your devices. An alternative to Google Cloud, Apple's iCloud or Microsoft Office.

Support
Yes

This badge describes how much love and support this service gets from the pub.solar community. Services with a higher level of support are less likely to suffer from outages or dataloss.

We consider this service to be part of our core. It is among our highest priority services to keep it online, up-to-date, and backed-up. This service will not be shut down without at least 3 months of prior notice.

Backups
Yes, untested

This badge shows whether the data in the service is automatically backed up every day.

We run daily encrypted backups to an offsite location, but we do not have automated tests to see if recovery works. In a catastrophic event, recovery might take a long time.

Anonymous usage
No

This badge shows whether you can use the service without registering a pub.solar ID.

You have to log in with a pub.solar ID to use this service.

Zero knowledge
No

This badge tells you how much access the pub.solar administrators have to your data in that service.

All your data in this service is readable by pub.solar administrators.

By default, no data in Nextcloud is encrypted and everything is readable and changeable by pub.solar administrators.

However, we have installed the End-to-End Encryption app which gives you the option to encrypt files before they are sent to the pub.solar cloud.

This application has horrible reviews, with lots of people saying they suffered dataloss. Though we offer this option, there will be no support or help if you use this app and lose data.

Logging minimized
No

This badge tells you whether we have configured the service and any related software so it logs as little data as possible.

This service runs in its default logging configuration.

Decentralized
Yes

This badge shows whether this service can interact and federate with services of similar types hosted by other people or organizations.

For example, you can send an email from your own provider to someone who has their address with some other provider. With facebook messages you cannot do this; all facebook messages have to go to other facebook users.

All relevant communication features of this service can interact and federate with other instances of similar services.

Storage encrypted
Yes

This badge tells you whether the service data is stored on encrypted drives. This protects against unwanted physical access to the servers, since only the pub.solar administrators can unlock the hard drive encryption.

Caveat: Man-in-the-middle attacks that intercept the password in-transit when pub.solar administrators remotely unlock the disk can circumvent this. Do not rely on storage encryption to keep your data safe from highly-capable attackers like nation-states. Focus on the zero-knowledge badge if this is your threat-model.

This service runs on a server with encrypted hard drives.

Mastodon ↗

Social networking and microblogging. A decentralized alternative to X (Twitter).

Zero knowledge
Partial

This badge tells you how much access the pub.solar administrators have to your data in that service.

Some of the data of this service is unreadable to pub.solar administrators, but not all.

By default pub.solar admins cannot read your messages, but there is metadata that is accessible:

  • Who you are talking to
  • When you are talking to them
  • When you are online or offline

Also, some larger public rooms are unencrypted, and you have the option to turn off encryption on rooms you control.

Support
Partial

We have been running this service for a while, and it is probably going to be around to stay. However, it is not our highest priority. We could shut this service down with only a couple of days of prior notice.

Backups
Yes, untested

This badge shows whether the data in the service is automatically backed up every day.
