Housekeeping: Strange Behavior
No, we don't mean the markets. We ran a server changeover last night which meant tampering with some DNS settings. As a result you may experience dizziness, hot flashes, and issues with logins. You might try (in order):
A cold compress.
Clearing your browser's cache and/or waiting for the DNS update to gel with your local ISP.
In any event, the symptoms are temporary and will abate in their own time. If you continue to have trouble, drop Marla an email via marla@zh.
