The recent outage impacting Pear Deck services has been fully resolved. DNS records have now propagated across networks, and access to Pear Assessment should be restored for all users.
If you continue to experience any issues, these are most likely related to local network or device caching. In those cases, we recommend clearing your browser/device cache or reaching out to your IT Administrator to flush local DNS records.
We sincerely apologize for the disruption and appreciate your patience while our team worked to resolve this issue.

Update
Reports of DNS issues have continued to reduce
We are continuing to receive a small number of reports of Apps being unavailable for some users. We are continuing to monitor the situation and will provide further updates as we discover solutions.
If you are using a School or District managed computer please reach out to your IT staff and forward this notice to them for assistance restoring access.
Many Districts and Schools have reported success resolving access issues with these previously communicated fixes and some additional steps:
1. Clearing DNS Caches across the network (https://support.goguardian.com/s/article/Resolving-DNS-Propagation-Issues). NEW: Some customers have found they have unexpected DNS servers provided by Software Defined Networking controllers, Wireless access points, and other IT equipment. These need to be cleared or disabled as is appropriate for your network.
3. NEW: For Chromebooks specifically: If DNS Caches do not clear from Chrome set a manual DNS override for the network connection, saving, and reverting. This seems to force the OS cache to clear.
4. NEW: To resolve Pear Assessment incompletely loading: Close all Pear Assessment browser windows, clear the Browser Caches to remove corrupted Pear Assessment assets, reload the app.

Update
DNS issues appear to be focused in customer DNS deployments and at the Operating System and Browser level.
If you are using a School or District managed computer please reach out to your IT staff and forward this notice to them for assistance restoring access.
Enterprise Customers can reach out to our support to be connected with a Engineer for assistance.
Our monitoring scripts no longer detect invalid DNS records at the ISP and Public DNS level. We have reached out to customers and have found that their own DNS deployments may still be providing invalid records. Highly available deployments have had issues where just one of several servers in a DNS deployment have failed to invalidate the incorrect records and create downtime.
DNS propagation issues have continued to improve since the last update.
Level3 Communications, a large DNS provider for home and business Internet Service Providers, cleared their DNS cache at roughly 5PM Eastern Time. Other smaller DNS providers have cleared their caches as well. We believe that caches will continue to clear in the coming hours. We are continuing to scan for invalid records and will attempt to contact DNS providers when possible to correct the issue.
Customers with customized and/or internally hosted DNS deployments have had to verify and correct internal DNS systems. Of specific note is to verify that when multiple DNS servers have been deployed that they all have up to date records. The instructions linked below can help System Administrators with these issues. We will provide updates to this guidance in the morning if new information is available.
If you are still affected, Action is Required:
IT Administrators are requested to clear DNS caches both locally and on any caching DNS proxies in use. This may include:
Local computer DNS caches Network-level caching DNS proxies Content filters VPN services
Note: You may still experience intermittent outages until full DNS propagation, the updating of our DNS information is complete.
