No, it's not the problem of MEW, it's the problem of Bancor network itself. Bancor network crashed during crowd funding. Not the MEW.
That doesn't explain why folks had trouble sending ETH from POLO and other exchanges to MEW.
Yes it does, MEW tx traffic during Bancor ICO was off the chart, see the post above with the chart from the MEW tweet. (EDIT: see this link here

what I want to know is if Bancor extended the 1 hour window to 3 hours, how come my purchase got cancelled during that time, and who do I harrass at Bancor about it.
My point is that it did affect the ETH network, because ETH transfers that have nothing to do with Bancor, were also negatively affected.
I succeeded to submit my first transaction within the first hour by some miracle. However, it got canceled after 30 minutes or so. This was after I tried several times within a second after the ICO officially started. I reached out to a friend. He advised me to use the Etherscan.io node. I did and the transaction went through smoothly. I then advised folks at the forums to do the same. Nonetheless, safe to say, the ICO was a mess given all the pending transactions (4600+ when I last checked).
I am sure it couldn't hurt to contact Bancor (
