Hi,

After the DDoS its been around 24 hours, yet the ping times seem to be a lot compared to before.

Earlier it was in the range of around 400-500ms but post the downtime it has risen to around 700ms

http://www.pingdom.c...ew/?name=Fresco

Any reason why?

Also is there any reason why Fresco has much higher ping time compared to other servers of MDD?

1. You shouldn't worry about what Pingdom gets for pings, you should worry about what *you* get for pings.
2. They're literally in the exact same cabinet, connected to the exact same switch so the PINGS are the same, it's the response time that can differ.
3. If you feel your site is slow, just open a ticket and we'll be happy to shift you to Gemini.

I just pinged all three, including my vps, and was surprised to see the ping times here from the west coast just a few ms higher than yours (averaging about 50ms on all four servers). I'm 1,000 miles away from the data center, about the same distance as Indianapolis, I guess. Since a blink of an eye takes 400ms, 50ms is pretty fast.

A tracert shows I'm routed through Roadrunner's servers to Los Angeles, then San Jose on Level3, then into Denver, so its a pretty direct route.

Yeah, we have no control over your forward route... If memory serves me (I could be wrong) you're on a VPS so if you want, log into it and ping your home IP :) If you're not on a VPS I can do it for you if you open a ticket and ask for me :)

I am on a VPS. I had not thought of checking the route from the server to me. Ping shows the same average of about 51ms, and the tracert looks to be the reverse routing of my forward route (home IP modified because I'm paranoid):

Thank you for the detailed description and option to shift to gemini. From my end the average ping on fresco comes to around 360-450ms while that on gemini comes to between 350-420. So I dont see much of a difference from my end. But most of my clients / users accessing the site are from US so if I see the pingdom pings there is a drastic difference. I think I will wait and watch before taking a call.

I'll be happy to show you pings from all around the country to any of the servers if you wish, I'll just have to get with people in different parts of the country and ask them to ping them and then ask for their location as well.

I'll do this over the next few days and post it up :)
