Hi @Leetcode.

Today, at the start of the Weekly contest:

1. The site got rate limited for straight 7 minutes.
   This means the questions were not accessible.
2. When the page finally started to load, the "Run code" feature started giving "Unknown error" and took more than a minute to show the execution results.
3. Each problem page took more than a minute to load and got rate limited initially.

This must have happened due to increase in number of contestants and everyone loading the contest at the same time.
Please provision the servers in advance looking at the number of contestants so that the contest experience is better :)
