Sometimes bot failes. It looks like this:

Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/telebot/util.py", line 59, in run
    task(*args, **kwargs)
  File "/usr/local/lib/python3.5/dist-packages/telebot/__init__.py", line 276, in __retrieve_updates
    updates = self.get_updates(offset=(self.last_update_id + 1), timeout=timeout)
  File "/usr/local/lib/python3.5/dist-packages/telebot/__init__.py", line 246, in get_updates
    json_updates = apihelper.get_updates(self.token, offset, limit, timeout, allowed_updates)
  File "/usr/local/lib/python3.5/dist-packages/telebot/apihelper.py", line 180, in get_updates
    return _make_request(token, method_url, params=payload)
  File "/usr/local/lib/python3.5/dist-packages/telebot/apihelper.py", line 54, in _make_request
    timeout=(connect_timeout, read_timeout), proxies=proxy)
  File "/usr/local/lib/python3.5/dist-packages/requests/sessions.py", line 524, in request
    resp = self.send(prep, **send_kwargs)
  File "/usr/local/lib/python3.5/dist-packages/requests/sessions.py", line 637, in send
    r = adapter.send(request, **kwargs)
  File "/usr/local/lib/python3.5/dist-packages/requests/adapters.py", line 529, in send
    raise ReadTimeout(e, request=request)
requests.exceptions.ReadTimeout: HTTPSConnectionPool(host='api.telegram.org', port=443): Read timed out. (read timeout=30)

There are many cases with the same problem in the internet. Telegram servers may be sometimes anavailable so it causes this kind of promblem.
