I have an online store hosted on a co-located server. 2-3 times the server was down and I noticed the following: 1. the server goes down (one it was because of zone file, the other time of not enough RAM - because of another site which is removed now) 2. the server is fixed and up, after about 2 hours max\ 3. no orders in the online store - after some days the orders come again? Is it possible the net providers to cache the site down version and users not to be able to make order for some days or something like that?
I assume you were getting orders before your outages? Or could it be an anomaly. Your last statement is a bit confusing. Services will not "cache" a downed site, typically only good static data. Have you checked to make sure the online store functionality works from various source IPs and that it is actually accessible?
Do you know anyone who might could place a test order? I mean if everything is working on that end, then there's nothing really wrong. Let me ask you this, do you do your own nameservers?
I doubt there is any cache there. When the outage happened, did you try to make a trace to your server? How did they be fixed?
Yes, I asked many friends from different locations to make test orders - no problem. Yes, I do my own nameservers on different domain on my server.
When I traced it tru a free trace service online and everything was alright. The server admin fixed the zone file, then a bad script was having many queries - stopped..
