I'm not experiencing any problems and i've been using Numista heavily at all times of the [GMT] day for the last few weeks with no problems - It's always been very quick here.
That said, those of you who are having problems appear to be in the US? (Correct me if i'm wrong) Of course, the server is hosted in france, so that -is- a long way geographically, and could be related to bandwidth or latency issues, which may or may not be related to your ISP (But rather your ISP's access to US <> European backhauls). Just because you pay for faster bandwidth and faster performance doesn't mean it isn't a problem with your ISP at all, but rather it 'should not be' a problem there - very different.
I assume you're not having problems with other sites, and you've tried it with other devices from your connection.
I believe Xavier has recently shifted static content, i.e. images to a Content Delivery Network (CDN) provided by ovh.com (
http://www.ovh.co.uk/cdn/cdn-network-map.xml) - Which means these resources will be hosted in numerous places around the world (Not necessarily all of those in the link above - depends on packages), closer to you to help reduce lag, However dynamic pages such as the actual webpages your looking at and the database will not generally be available on the CDN - So every page load needs to go to france and back several times.
Some diagnostics are needed...
Your webbrowsers include some free tools to see what loads slowly -
In Chrome go to View > Developer > Developer Tools. A window pane should appear, click the Network tab and load a numista page.
What you'll see here is each individual element that loads showing when it started loading and finished loading. Most info here can be ignored but the 'time' column is sortable. For me, the entire page (the numista homepage) loaded in 1.8 seconds - The longest element actually unfortunately being XITI image at the bottom of the page. If you see anything taking ages if the 'path' is 'numista.com' then its coming from the main numisa server, if its static-numista.com then its the CDN.
See what you find there.
Other things to try out if that doesn't shed light are pinging the server (google 'how to ping a website') and possibly 'traceroute' which shows the latency between your device and every router that is between you and numista.
It is unlikely [but not impossible] to be the main numista server at fault (As it's working fine here) - But rather one of several factors:
* Your ISP - Either rate limiting, or otherwise bottlenecking from You > ISP or ISP > European backhauls.
* The other numerous backhaul ISP's from your ISP to the Datacenter where Numista or its CDN locations is located.
* Your home personal home equipment, Your PC, Your Router or something. Including any AV software, spyware or other software which may interfere.
* A resource that numista loads, such as the ads, the XITI webstats checking etc which would hold up page load, but aren't necessarily Numista's fault (But nevertheless part of their problem).
* Numista's server ISP and it's link to US backhauls.
Without being able to replicate the problem it's hard to say exactly what's at fault but some of the diagnostics above should be able to help, or at providing us (PM?) the output of the tools may help us diagnose the problems for you?
Happy to help further if I can...
