Unexpected downtime today (10-14)
14 Oct 2013 05:52 pm
Members, we would like to apologize for the unexpected downtime today. We had some issues with our DNS server and ended up changing DNS hosts, this caused a much longer than expected site outage.
Tasks, Offers and Surveys may not give credit instantly due to the DNS propagation not being completed yet. If you are not credited for completing an offer or tasks please note they are being tracked and you will be credited once this issue has resolved itself.
Again we apologize for any inconvenience this issue may have caused.
