What network are you on? I'm outside Mataro and with Vodafone, got internet connection and power restored some time early morning/late night (after 02:00, before 09:00)
Ouch, that sucks. Bet their technicians are on overtime already too :/ I'm guess you've already tried the true-and-tested "Turn off, wait five minutes, turn on again"?
Usually we've had lots of issues with our fiber from Vodafone (like random ~70% packet drops from time to time) but happy Vodafone seems to have recovered quickly in this case, no GPON issues here as far as I can tell.
