I've been running my ticker-bot to gather order book from Stellar Network. However, it did not work since probably few hours ago.
The bot is tiny program written in Python which just pinging orderbook using curl package.
import pycurl
from io import BytesIO
buffer = BytesIO()
c = pycurl.Curl()
c.setopt(c.URL, 'https://horizon.stellar.org/order_book?selling_asset_type=credit_alphanum4&selling_asset_code=MOBI&selling_asset_issuer=GA6HCMBLTZS5VYYBCATRBRZ3BZJMAFUDKYYF6AH6MVCMGWMRDNSWJPIH&buying_asset_type=native&buying_asset_code=XLM&buying_asset_issuer=native&limit=10')
c.setopt(c.WRITEDATA, buffer)
c.perform()
c.close()
body = buffer.getvalue()
print(body)
The result is, blocked by Cloudflare (masking IP by hands):

I heard some kinds of DDOS attack was happened few hours ago. Surely, I'm not a DDOS attacker. I've been pinging above query every seconds and it worked for months. Even when I pinging orderbook by using curl in bash shell same machine, it retrieves orderbook correctly.
# curl "https://horizon.stellar.org/order_book?selling_asset_type=credit_alphanum4&selling_asset_code=MOBI&selling_asset_issuer=GA6HCMBLTZS5VYYBCATRBRZ3BZJMAFUDKYYF6AH6MVCMGWMRDNSWJPIH&buying_asset_type=native&buying_asset_code=XLM&buying_asset_issuer=native&limit=10"

Anyone could help this? I will really appreciate for this.
