Update
We're starting the migration process now.
Posted Aug 19, 2017 - 10:37 PDT
Update
The migration hasn't started yet as we're still working through our pre-maintenance checklist. We now plan to start the maintenance at 10:00 PDT (1 hour later than planned). We still expect the migration itself to take around 20 minutes.

Will provide another update when the migration starts.

In progress
Scheduled maintenance is currently in progress. We will provide updates as necessary.

Scheduled
Starting at 9 am PDT, we will be migrating many of our databases and app servers to a new datacenter. During this time, the API tier will still gather and accept occurrence data however the REST API will be put into read-only mode. The web tier will also be put into read-only mode and it's likely that it will be unavailable during the migration.

We expect the migration to take up to 20 minutes. During this time, processing delays will increase and notifications will be delayed. We will update this page with progress info during the process.
