Long short , as you said "The solution is for the gateway upgrade their system and server, while Lazada think about wallet issues."
But I think , as for laz wallet , they will able to fix it easily but as for gateway , it's be an upgrade which will take maybe next year.
Besides , bank also involve on online transaction failure.A lot of them able to pass the payment with OTP , how could this happen ? .It is more like a loop hole or bug.It's a security issue.What is the use of OTP when you can get pass OTP on the payment ?
Total mess up for all payment system.Saw , only best was paypal , second 7-11 then wallet and finally to all CC transaction if we arrange the failure rate.
Nothing we could do , just avoid 11.11 that's all.
My guess is around 300k transaction made per second at 12am where infinite loop happen from gateway to wallet and to laz apps.
Laz apps can't handle traffic beyond.It's more like a DDoS on all those server for them and their system filter it all.
Looks like total failure , I don't see why laz fbook still said they achieve million of order.I assume it count together with private order from company to mall.
Anyway , everyone already upset , not to mention on 12.12.Worst part is $ stuck can't by anything as someone said , if you bought an item at CC and stuck at payment buy CC pass already by laz said item cancel.GG
No more $ to buy since the refund was drop to deposit wallet and not able to refund back.Without item you wanted to buy OOS , no voucher and $ stuck inside and CC will charge for interest because it was not refund back to CC but back to wallet.
Hopefully problem will be solve at 12.12 .I only predict will have payment system problem but didn't know all payment method was affected and took about 12 hours to fix.
And after 12 hours , someone still experience problem.
btw, MCMC and KPDNKK also must complain to gether.Even though MCMC was ISP related , who knows the OTP sms was congested on the telco or isp nat firewall block the payment system flag as ddos ? MCMC does handle security on banks too.
Ya, first, order is order, I guess they count failed order also.

For the OTP, so far I know the design after you key in the OTP(TAC) and submit, the server will contact Lazada server that you had confirm to make payment, if the Lazada server said yes I know, then it will count as success and deduct money from your card by telling your bank system etc.
I also trying to pay for Taobao at 11.11 morning, and lucky get a few failed respond from MOLPAY which is also using FPXPAY while I am paying via online banking.
As I don't really try to discover in this area, but I think it can be they messed up the transaction with other customer transaction, if their design is having bug.
When your system is not ready for extreme high load that count as DDOS, bug will shown up, that's why they normally choice to turn off the server or block the DDOS traffic outside the firewall, as they want to protect the server being memory overflow.
But you can't, as it is money.
For Lazada, the resource is dynamic allocated like other servers, when you can't load the pages, it is because it is such a very low priority compare to handling of payment.
Which indirect showing that Lazada might also causing this issues, as they are also out of resource to handle this, maybe some of them has been using as CDN servers for Taobao, so it out of resource.
For the filter, it should be not blocking, if it is blocking, you will see the sliding for human verification.
And I don't think it will stupid enough to show this sliding page to payment gateway, or it will be funny.

As Paypal is their own gateway, means the Lazada connect to Paypal server, so I guess they already ready for it, but I guess there are still some failed transaction at 0 AM.
And for other payment excluding COD, 7-11 always mess up when everyone is grabbing it for holding discount order long time ago, so less customer and well, they has less report as no one willing to using it on high traffic time, but at least Lazada is connecting to their own gateway directly.
For CC and online banking should be the same gateway? I had such a very long time not using them after I found out Paypal is the best.
If yes, then yup, I think 95% of people using it, and kaboom, just like last month on Shopee, they also die on the payment gateway.

Yes, many lost their promotion price because of the suck of payment, specially CC.
Lot of them has sucked on waiting 24 hour verification, and can't choice other method to re-pay again.
And the worst?
They never know it will released back to public after 30 mins.
For people that paid for it but it get sucked and found out later in the wallet, ya, bad luck.
Trying to pay higher promotion price using wallet and get cancel again? double bad luck.

And ya, forgot about MCMC handling that case too, no having clear mind after having 11.11 event.
