Scheduled Maintenance
In order to increase the stability and scalability of our core systems, our Midwest data center will undergo SCHEDULED MAINTENANCE Sunday, May 8th from 9PM to 1AM MDT. SMTP and API mail sends will be routed through our West Coast data center so mail will still flow during this time. The following applications and APIs may see slowness, errors, and sending delays for 60 minutes:

- Legacy Newsletter
- Marketing Campaigns
- Sendgrid.com login
- New account signups/upgrades

While unlikely, the following may occur for 90 minutes during this window:

- Legacy Newsletter sending delayed
- Legacy Newsletter site down
- Legacy Newsletter APIs down
- Marketing Campaigns sending delayed
- Marketing Campaigns site down
- Marketing Campaigns APIs down
- v3 APIs down (mail send will not be impacted)
- Sendgrid.com and account login down
- Free and Paid Signups down
- Recipient unsubscribes down
- Parse API down
- Stats delays

Thank you for your patience through this maintenance. Please contact our support team with any questions: https://support.sendgrid.com/hc/en-us.
