The 185.27.134.155 also appears to have been down for a while today, showing similar outage patterns suggesting a DDoS attack. It has been up for a some time now though, so I think the attack is over already.
I checked our metrics but I donāt see any issues like this having occurred on 185.27.134.177. So I donāt know what issues youāre experiencing, but it doesnāt seem like that IP address is being attacked.
