signup.dat.com redirect failures and strange behaviors

Updates

    Direct access to legacy signup.dat.com URLs is intermittently failing with blank pages / net::ERR_CONNECTION_RESET instead of redirecting users into ssu.dat.com as expected.
    The incident is not related to the CSB DB cutover. login.dat.com now redirects to ssu.dat.com via a rewrite rule in Cloudflare. SRE has documented the steps for this fix and we will eventually remove it in the future after links on dat.com sites are updated.
