I am having a very hard time understanding why they have not yet implemented redundant databases and sites. This takes us down because we use their return information to perform real-time processing and credit checks.
Our backup processor is Paypal Web Payments Pro and they are down now too so we are basically screwed until one or the other comes back up... not a good situation. Apparently I need to look into another backup system. I really don't understand how linkpoint, a firstdata service, can go down so often.
We really need to find a system that will be up 99.999% of the time (as our site is) to process our transactions and validate address information and cvv / cvv2 information real-time so that we know the card is good before letting a customer complete the order.

One thing that is essential in your programming is some sort of error capture that notifies you immediately if there is a problem. I have several - if it connects to Linkpoint and L.P. returns an error, or there is no response or a timeout, this is logged and I'm immediately auto-emailed of the problem. Sorry to say, I've only seen two of these in two years, so not sure what's going on with you.
We have a secure cert and are processing transactions via silent post - maybe you're using the processing on the Linkpoint site?
We were able to take some action to temporarily just record the cc numbers until we could process them later so this was transparent to the customer but we had lots of transactions that required same day shipment and we could not verify payment until late in the day so this put us in a serious bind.
My link was removed but if you go to linkpoint's primary website and go to the gateway status you will a stoplight graphic that shows network status. As soon as we found our processing down (which was nearly immediate), we checked the gateway status and their own stoplight graphic showed that their network was down and was not restored until about 4pm the same day.
We intend to change our code such that the cc processing system on our side performs a gateway status check. If it fails, it will automatically revert to cc# storage mode until the gateway comes back up again so that we do not risk losing sales as we determine that the gateway is down (via our notification system) and switch over manually to a cc# recording mode). An alternative is not to perform real-time validation of the card but we prefer to do this to prevent the headache of calling or notifying thousands of customers about zip code, expiration date, adress, etc problems.
Glad to hear your service stayed up but ours was down and their own site indicated that they were down. In our time with linkpoint, which has been about 18 months they have gone down about a dozen times and their status has indicated such (they also send an email later about the problem if you turn on their diagnostic messages). This is the only time we have been down for the majority of a business day.
