Like a majority of Magento ecommerce users, I call realtime API quotes from FedEx/UPS/USPS to get the shipping rates. The majority of the time, everything works okay. However, on occasions the API goes down (scheduled maintenance or randomly).

Scheduled maintenance, the administrator can go ahead and set a flat rate or table rate ahead of time. However when it randomly goes down, this can cause a massive headache. An example of this, is when Fedex went down for 57 minutes on Black Friday (Source). This affected approximately 200 customers/orders.

I am thinking of either finding a extension or writing my own that calls one API (lets say FedEx), if Fedex doesn't respond within 3 seconds, it will attempt to call the API of UPS. Of course there will be mapping involved (Fedex Ground = UPS Ground and so on) and I know the quotes price won't be exact (FedEx might be $6.75 and UPS might be $7.35), however I am attempting to give the customer a shipping quote without them noticing a problem or a problem that prevents them to checkout.

My question is, how do other Magento sites prepare for this? Do you have failsafes? Are the failsafes done manually or programmatically?

    Many of our clients use a manual fail-safe by either enabling another real-time option, or having a shipping by weight/currency table ready to go. You can use a service like www.ShippingAPIMonitor.com to get notified when shipping outages occur. Jan 18, 2015 at 21:28
  • We recommend having a fallback that's a static rate based on price for those instances. These outages happen often enough to where it's worth being prepared. Another solution is a multi-carrier API since they're rarely all down at the same time. Jan 19, 2015 at 17:30

The downtime of live carriers tends to be extremely rare, some are obviously worse than others, but up until recently UPS, FedEx were very stable.

There have been a few issues with FedEx recently, probably to do with Dimensional Changes going in, we have raised bugs/problems with them, and I know we have had live site outages. But in general it 'shouldn't happen'.

Saying this we have worked with customers in putting in backup carriers (it's more of a problem with Freight), and have solutions, but I can't discuss here as will get kicked off. What I can say is that there are solns out there.
