Old BTC theft, from May 2014,but the way hackers did it looks very similar to BTER theft. Unfortunately, BTER site is not at dedicated servers,but on same servers as hundreds of other websites.It made significantly easier for hackers to robbed them.
Would it matter where they host their web services if a cold wallet was compromised that was supposedly not there?
it does, for bter, the private key of the cold wallet was not compromised
the process of transferring bitcoins into hot wallets was compromised so in a sense if you are hosted on a non secure platform, your hot wallet address could be changed to empty your cold wallet
