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.
Yes, the news is propagating in a different may people scared about whether MEW is not accessible. I think there is no problem with the MEW the problem raised with the Bancor network only.
It was not a complete failure of the MEW network or that Bancor's network crashed. Parts of the ETH network were affected by the out of action nodes at MEW - probably due to attacks or simply too high transaction volumes. However, not all nodes at MEW were affected. Bancor related transactions via the Etherscan.io node went through smoothly via MEW.
