Our DNS provider has mitigated the issues and so we have re-enabled DNS changes through our API and UI. If you created or modified any records in our Hosted DNS service between 1600 UTC and 1745 UTC, you should confirm them with a dns lookup and if the response does not seem correct, remove and recreate them. Note that our system automatically creates records as you apply custom domains and domain aliases to your sites, so if you see a name you applied to a site in our system not working well during those times, you would instead remove and re-add the name in the Site's Domain Settings panel. Our support team is standing by in the helpdesk (email@example.com
for our paying customers) and our forums (for our free customers) to help if you have any trouble!
