Website Under Heavy Load Error
Incident Report for Summit Learning Platform
As of today, we are confident that we have resolved the primary cause of the intermittent site outages. To be certain, our engineering team will diligently observe the site over the next few days. We are optimistic that this issue has been fixed.

Building on the work we've done over the past week, we are doubling down on our efforts to reinforce our infrastructure so we can improve the platform's reliability in the long-term and prevent any future incidents. Some of these updates might result in some temporary bugginess in the platform, but our engineering team is prepared to address those issues quickly if they arise.

We are appreciative of your patience, partnership, and understanding over the past week. We are deeply committed to delivering the best learning experience to you and your students - it’s our purpose.

Thank you.

Over the weekend, we identified and removed the changes we believe caused the intermittent site outages last week, and added in new fixes to prevent future Platform instability.

In order to make sure those fixes worked, our team is monitoring the site closely, and we are ready to address any unforeseen issues if they arise.

Thank you for your patience, resilience, and understanding.

Yesterday evening, we released a limited set of updates to help improve our site reliability. Despite these updates, some users still were unable to use the platform today from 8-9:30 am PST.

We will be releasing technical fixes soon that will fix the immediate cause of the site issues from this week, and we will continue debugging the site over the weekend so the site is ready for Monday.

Thank you for your patience, and we will continue to update this page as we have updates.

Most users should now be able to access the platform, but our team is still investigating the root cause of this issue. We are identifying which parts of our infrastructure need to be reinforced in order to best meet our increased traffic, and we will be working toward making those improvements as soon as we can.

We will continue to update StatusPage as we get closer to resolving the root issue. For now, if you run into errors, please try refreshing the page. If that does not resolve the issue, do not hesitate to reach out to
