Can a faulty DNS record prevent networking?

My server's network interfaces are not available anymore since yesterday evening. I didn't change anything, but I added a new DNS-record shortly before.

Unfortunately, the web interface I used to add this DNS record escaped some characters, so I've got a faulty DNS record:

example.com 86400   IN      TXT     "\"v=spf1 mx a -all\""

However, this is the only unusual thing I could notice about this.

Is it possible that the \-characters in my DNS record are confusing for some routers? Or could it be the system itself which is confused by this (it's a Debian Lenny system).

Unfortunately, I can't quick-test it because of the long TTL of the record.
