Thanks for the note, but although there are definite outages on your end, the most common issue conitnues to be anti-virus programs like Avast, AVG, and others flagging SEDOPARKING.COM as hosting "URL Phishing" (or similar), which is likely due to a dodgy ad sneaking in.
This entirely blocks all sites hosted at SEDOPARKING.COM on the computers that use these anti-virus programs, and it's especially punishing for those (like me) who simply forward to a Sales Lander without ads. Guilt by association, I guess.
Your team needs to be monitoring each AV environment, and when a Sedo blacklist happens, contact said anti-virus site/forum with a request to whitelist SEDOPARKING.COM. A potential future strategy is to create a secondary set of nameservers such as SEDOLANDERS.COM for those who will always use landers 100% of the time and will only forward to landers - those who want to switch back and forth between Parking and Landers can still use SEDOPARKING.COM.
I propose this because the anti-virus blockages are becoming more and more common, and are taking longer to solve (the last time you guys were offline on AV user systems for 3-4 days). thus making Sedo a very risky and unstable venue to use sales landers under your parking-based hosting system.
