Blockchain.info is notoriously known for their buggy block explorer and wallet. It could be that your transaction isn't even broadcasted on their end but on other block explorers it already is. You're not the only one having this problem, though, having checked reddit and this forum concerning the recent problem.
Guess you have to try other accelerators that doesn't depend on blockchain.info's explorer.
Update1:
I was extreamly lucky, I have just managed to include the tranaction into the ViaBTC accelerator for free, so it seems they see the transaction. (I hope they don't rely on blockchain.info but have their own blockchain interface, they are big enough to have their own system for this...)
But let's wait for ViaBTC to find their first block in this hour to see if the transaction has been included or not.
Edit:
Just found the first block, the transaction is included, it has the first confirmation
Thanks for everyone, it seems it's only blockchain.info that has a bug or something, but there's no problem with the other parties.
Edit2:
The transaction is visible in blockchain.info now, right after it has it's first confirmation. Weird...
