| High room temperature will easily cause the hardware malfunction: Your host needs to be on in 24 hours. As all the components are electronic products, the host must be placed in the 24hour air-conditioning room, to ensure the hardware running won’t produce malfunction due to long-term use. |
| Two |
| Loss caused by power cut：Your company or house shall be equipped with UPS, so that the system won’t be down due to power cut, which may destroy the system and stop the website running. The common UPS can work only about 30-40 minutes. Can you ensure the power will be recovered within half an hour in case of power cut? |
| Three |
| Electricity bill burden caused by host：
The computer needs to be on in24 hours, which will certainly cause high electricity bill of your company or house. The power company makes different bill degrees according to the operation or non-operation use. One more computer may result in higher unit price of the electricity.?

| Your computer is on the risk of attacks and intrusions：due to the lower security of the computer in house or company, the computer data may be disclosed by Trojan embedding, virus attacks, and hacker invasion. Be cautious that the host in house or company might be taken as the platform by the criminals to attack others, which will make you involved in the lawsuits. |
| Five |
| No firewall installed in house：In recent years, the DDOS attacks are prevail. Large DDOS attacks cannot be prevented by common firewall of several hundred thousand ntd. It mainly depends on the traffic volume of the attacks. Provided that the network installed in your house is of 10M/2M or 12M/1M, 8M/640K, the hacker just needs dozens of M traffic to attack you if he knows your IP.. Then the host or website of your company will be in meltdown, because the entire network bandwidth is occupied by the attack data. |
Remarks：
The biggest benefit of using DANET Intrusion Prevention of computer room(http://www.danet.tw/service_soc.asp ) is that Chunghwa Telecom detects these hacker and virus attacks from the source side of the machine room, and defend them in real-time. In this way, it guarantees your host and network work smoothly. |

| Wastage rate of network bandwidth：When applying for ADSL or FTTB in the Telecom Companies, some users might be informed by the customer service staff that your house is too far away from the machine room(more than several kilometers) to install the network of 8M/640K or 12M/1M. That is because the network transmission signal can cause some wastage due to the distance. If your house or company is far away from the machine room, you will get less bandwidth. 12M/1M might become 8M/640K when reaching your house or company. |
Remarks：
A、For the common asymmetric bandwidth such as 10M/2M, 8M/640K, 12M/1M, and 2M/256K,
Please pay attention that Telecom Companies don’t guarantee bandwidth.，
It is a kind of shared network bandwidth with the compilation ratio of 4:1. We assume the
ADSL switch in the machine room of Neihu district has 1G bandwidth egress. Even if the
total of all ADSL users in Neihu district is 4G/1G, their traffic can only go through the 1G
egress of the switch in Telecom Company. That is the compilation ratio. During the general
peak hour, your network must be in traffic jam. If you doubt it, you can ask the Telecom
Company whether your network has bandwidth guarantee.
B、The benefit of co-location in DANET machine room is that your host is placed in the source
side of the machine room, so you don’t have to worry about the line will pass the drains or
rural paths, even the cable is destroyed by the projects on the road, which may cause
network disconnection. |

| When the host has some malfunctions, you cannot find professional engineer to handle it immediately：Most of the bosses or individuals are not MIS or IT engineers, nor program designers. Thus, when your customer complains the host cannot be connected, and you have no idea about it, and when you call outsourcing engineer or friend familiar with computer, and no one is available or no one gives you a hand, it is a bit useless for your regret then. If you hire someone to fix it, it might cost thousands ntd for one on-site maintanance. Actually, the problems of the host are generally small, which might be fixed through rebooting within 3 or 5 minutes. So it is very important to place your host in a good co-location company. |

80% of the Taiwan netizens are of HiNet, so choosing the co-location in Chunghwa Telecom machine room can ensure most of the netizens to connect your host with the fastest speed. The users can visit:
