Having problems with Proton Calendar? What can you do?

  1. First, stay calm.

    • We know it's stressful when Proton Calendar is down, but running around is not going to fix it.
    • Remember that it's normal for services to go down sometimes. It can be for a number of reasons, from maintenance to unexpected issues.
  2. Make a quick evaluation of the impact

    • Try to evaluate the impact of the outage on your business. Is it impacting a majority of your users or just a few?
    • Did Proton Calendar already acknowledge the issue? And published a status update? (You can find it in the top of the page or in Proton Calendar status page)
    • If not, understand if other users are also experiencing issues. You can also check this information on the top of the page.
  3. Communicate with your team and users quickly

    • If Proton Calendar is having problems and impacting your business, it's important to keep your team and users informed.
    • Share this page with your team, so you can start incident response procedures. No need for everyone to go around searching for information. Create a post or a specific channel in your internal communication tools (Slack, Teams, Google Chat, etc.) so you can aggregate all the information in one place.
    • If you have a status page, create a status update to inform your users about the issue. This way they know what's going on and you can avoid a flow of support requests overburding your team.
  4. Understand the root cause

    • After the first communication, let's move on to the next step. Do a more thorough investigation to understand the root cause of the issue and impact.
    • Reach out to the service provider to understand if they are aware of the issue and if they are already working on it. You can reach them in their support channels, or their social media channels if they have any.
  5. Is there any mitigation for the issue?

    • Understand if there are workarounds or mitigations for the issue. Can you use a different provider? Is the switch easy to do? Talk with your team to understand the best course of action.
    • Need to wait on the service provider to fix the issue? Understand if there is a timeline for the fix. Adapt your communication with your team and users to the situation. It's very important to keep everyone informed.
  6. Service has recovered?

    • Continue to monitor the situation. A lot of times, the service can see a brief recovery and declare the issue as resolved, but it can come back. Keep monitor for some time to make sure it's really resolved.
  7. Post-incident analysis

    • Once the issue is resolved, it's important to do a post-incident analysis. Understand what went wrong and if it's possible or needed to do something to prevent it from happening again.
    • Sometimes if it's a critical dependency, you might need to have a backup plan in place to avoid a similar issue.
  8. Prepare for the next incident, because it will happen again

    • Start monitoring your dependencies. Sign up to IsDown and aggregate all your dependencies status in one place.
    • Nowadays, it's very common to have a lot of dependencies, and keeping an eye on them is not an easy task. IsDown can help you with that, by aggregating and monitoring all dependencies status and alerting you if they are having issues. Create status pages to communicate with your team and users.

How IsDown compares to DownDetector?

IsDown and DownDetector help users determine if a service is having problems. The big difference is that IsDown is a status page aggregator. IsDown monitors a service's official status page to give our customers a more reliable source of information. The integration allows us to provide more details about the outage, like incident title, description, updates, and the parts of the affected service. Additionally, users can create internal status pages and set up notifications for all their third-party services.

IsDown offers an easy way to monitor Proton with maximum flexibility

Major Outages Notifications

IsDown monitors Proton Calendar for major outages. A major outage is when Proton Calendar experiences a critical issue that severely affects one or more services/regions. When Proton marks an incident as a major outage, IsDown updates its internal status, the customer status page and dashboard. Depending on the customer settings, IsDown will also send notifications.

Minor Outages Notifications

IsDown monitors Proton status page for minor outages. A minor outage is when Proton Calendar experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. When a minor outage occurs, IsDown updates its internal status and shares that information on the customer status page. Depending on the customer settings, IsDown will also send notifications.

Outage Details

IsDown collects all information from the outages published in Proton status page to provide the most accurate information. If available, we gather the title, description, time of the outage, status, and outage updates. Another important piece of information is the affected services/regions which we use to filter the notifications that impact your business.

Maintenance Feed

Proton publishes scheduled maintenance events on their status page. IsDown collects all the information for each event and creates a feed that people can follow to ensure they are not surprised by unexpected downtime or problems. We also send the feed in our weekly report, alerting the next maintenances that will take place.

Component Filtering

IsDown monitors Proton and all their 20 components that can be affected by an outage. IsDown allows you to filter the notifications and status page alerts based on the components you care about. For example, you can choose which components or regions affect your business and filter out all other outages. This way you avoid alert fatigue in your team.

Early Outage Indicators

Proton and other vendors don’t always report outages on time. Our crowdsourced status platform helps you stay ahead of outages. Users report issues and outages, sharing details on what problems they are facing. We use that info to provide early signs of outages. This way, even without an official update, you can stay ahead of possible problems.
