It appears we or some of our clients' sites are under DDoS attack today, flooding our site with bogus traffic that's shutting out legit connections -- like mobbing a store with decoy customers who don't buy anything, so legitimate customers have a hard time getting in to do business.
Our DevOps team is working on it, looking for any way to identify and block the bogus traffic to restore normal access. We thank you all for your patience and understanding while we wait out the attack and meanwhile work on solutions to fend it off sooner if possible.
