Thank you for contacting Geocaching HQ regarding connecting to Geocaching.com and the speed of the site. For the last few weeks, we've been tracking connection issues involving routing internet traffic between Germany and Seattle. While servers on both sides of the equation are functioning properly, our investigation has so far determined a sub-optimal routing path exists. It's beyond the control of our internet provider. Other websites that are hosted in Seattle and follow a similar routing path, including http://origin.rhapsody.com/browse, are also affected.
There are a few things you can do. Geocachers are having great success increasing their connection speed to Seattle using ZenMate and other VPN/proxy services.
In addition, please capture traceroute data (MTRs if possible) and forward them to your ISP (Internet service provider in Germany) for further investigation of your outbound-routing-path issues.
We'll continue to reach out to ISP's in Germany to lobby for increased speeds and connectivity. For the latest on this issue, and for additional information see our IT forum post.
