## 2016-05-01
|
||||
|
||||
- Since yesterday there have been 10,000 REST errors and the site has been unstable again
|
||||
- I have blocked access to the API now
|
||||
- There are 3,000 IPs accessing the REST API in a 24-hour period!
|
||||
|
||||
```
|
||||
# awk '{print $1}' /var/log/nginx/rest.log | uniq | wc -l
|
||||
3168
|
||||
```
|
||||
|
||||
- The two most often requesters are in Ethiopia and Colombia: 213.55.99.121 and 181.118.144.29
|
||||
- 100% of the requests coming from Ethiopia are like this and result in an HTTP 500:
|
||||
|
||||
```
|
||||
GET /rest/handle/10568/NaN?expand=parentCommunityList,metadata HTTP/1.1
|
||||
```
|
||||
|
||||
- For now I'll block just the Ethiopian IP
