All this fax-related-slow-bank-bla-bla stuff does not explain delays with the SEPA transfers. In order to make one, mtgox must have an account with an EU based bank. (I assume they have an account with a Polish bank, since they charge min 5 PLN of banking fee.) Usually, SEPA transfers ARE fully automated and it takes MINUTES for the funds to appear on the account. It makes me think that they are broke and make withdrawals (if any) from newly deposited funds.
SEPA transfers take D+1 days, not minutes. The explanation for SEPA delays can be found earlier in this thread (someone even called their bank to hear it from them), and everyone else are bored by hearing it over and over. SEPA has been delayed for the same reason since they changed to the Polish bank more than a year ago.
