Hello Yana. Thank you for your answer.
Yes, I'm monitoring my website each 5 minutes with pingdom and the average server response is about 700ms. The load page time is about 1.5 seconds.
I know your service is great. I've had no problems with your service for a long time and I know your server is an excellent one... but I had problems for a few hours and that's why I asked if the problem is in your side.
No other Enterprise users had the problem?
