On May 28th, the Chinese Internet ushered in a dark day. After Alipay appeared in a large area, unable to log in, transfer, payment and balance inquiry, Ctrip.com suddenly failed this morning. The official website and APP could not be used normally. The top of the website indicated that there was a problem and it was being repaired urgently. The cause of the failure was mixed on the Internet. Ctrip.com responded that some servers were attacked by unknown sources.
After a few hours, Ctrip.com is still in a state of paralysis. Ctrip's homepage will then hang out a notice, suggesting that users choose eLong.com. At 17 o'clock in the afternoon yesterday, some netizens reported that the eLong's homepage also began to be inaccessible.
It is reported that the eLong network suffered a large traffic DDoS attack after the Ctrip failure, and the website service was once affected. To this end, eLong Network urgently accesses the Tencent Cloud System to filter attack traffic and bring normal traffic to the website. Tencent Cloud Daxie System is a distributed DDoS protection system launched by Tencent Cloud. Each node is equipped with Tencent self-developed Aegis system with protection capability of 100 G-class equipment room. The attack protection points of Daxie are distributed in multiple cities across the country and are deployed independently. The total bandwidth of all equipment rooms reaches several T, which can ensure high availability of services.
Yesterday at 17:30, the media reported that the eLong home has resumed visits. At present, the attack traffic has been completely cleaned and the eLong service has returned to normal. The entire process of eLong's access to the Tencent Cloud Daxie system took only 14 minutes, and Tencent Cloud's ability to settle down through massive user security experience was once again verified.
