System Updates | The Official Blog of Site24x7

We are changing our ISP from Steadfast to Ubiquity for our New York monitoring location. Hence as a result, the IP address for the New York monitoring server will change. This change will happen from Feb 1st 2012, after which the old IP address for New York server will not be valid.

Old IP Address of New York Monitoring Server

67.202.79.132

New IP Address of New York Monitoring Server

173.234.70.166

If you have enabled IP restriction in your server, make sure that you add the new IP address into the allowed list. This change is necessary to ensure that our monitoring request carries on smoothly without any hinderance. If you have any questions, do contact us at support@site24x7.com.

Today morning (January 20, 2012), we faced an unexpected downtime starting 08:15AM PST to 14:25Pm PST due to a power failure in Equinix, our California data center. Polling did not happen during this time and even our website page was not accessible during this time period. The issue is resolved now and our monitoring services are back to normal.

Even though what happened was not in our control, we understand the difficulties it would have put you into. Please accept our sincerest apologies. We hope to provide higher resilience for our infrastructure in the future.

The following is a brief of what actually happened.

Equinix is the co-location provider in California for all Zoho services including Site24x7. The power failure affected our services. All these services including Site24x7 have multiple database clusters and each cluster has a Master-Slave-Secondary Slave combination. The power failure caused inconsistencies in some of the clusters and this delayed restoring the services.

We are still in the process of restoring the redundancies. Will keep you posted.

Update: Our website monitoring service is restored completely. If you face any difficulties, please contact support@site24x7.com or send us a tweet to @site24x7.

Yesterday, some of you might have noticed some strange behavior with Site24x7 service. First of all, let me apologize for the inconvenience caused. I will do my best to explain to you what happened and why it happened and how we are going to deal with this kind of problem in future.

The Incident

Yesterday around 12.30 pm PST, we had close to 3 outages at our IDC, the longest downtime being for 5 minutes. Our engineering team was able to get the server up and running within 20 minutes of receiving the downtime alert. But this doesn’t mean that the monitoring didn’t stop, there was some erratic behavior such as abrupt logging out of your account (if you have logged in during that period) and receiving downtime alerts even when website was up.

Once the problem was rectified, our monitoring system went on to work without any issues.

The Problem

After meticulous troubleshooting, we found the root cause to be failure of one of the router serving our link at our ISP (Internap) end. Unexpectedly our redundant link was also homed on the same router. Our ISP is analyzing the failure of the redundant link.

The Result

This affected our monitoring as we were unable to connect to the target monitored server. As a result of this, false alerts were generated from our system.

How to Delete the Downtime from your Report

You can delete these downtimes from your report by following the below steps:

Log in to your Site24x7 account
Go to the respective monitor dashboard page
It will list all the recent down time for the monitor under Downtimes table
Click on the X icon present in the right end of each downtime.

This will delete the downtime for the monitor.

The Learning

In addition to the existing checks for avoiding false alerts, we will also add additional network connectivity check to avoid this sort of scenario in future.

We will also refund the SMS credits to users who were affected due to yesterday's downtime.

If you have any further questions or clarifications, do contact us at support@site24x7.com.

Please make a note of our change in our IP address of our Spanish monitoring server.

Old IP Address	New IP Address
86.109.115.31	182.54.235.47

If you have enabled IP restriction in your server, make sure that you add the new IP address into the allowed list. This change is necessary to ensure that our monitoring request does not get hindered.

If you have any questions, do contact us at support@site24x7.com.

Update: Unfortunately, our upgrade process didn't go as smoothly as planned. Hence the old IP address of Netherlands is still valid. If you have white listed the new IP addresses, we recommend you to revert to ensure smooth and continuous monitoring from Netherlands server. We will keep you informed regarding the IP change.

We are in the process of upgrading our Netherlands (Rotterdam) monitoring server. As a result, you might face some disturbance in terms of monitoring capability from this location. We also like to inform you that we will be obtaining new IP addresses as a result of this upgrade.

Old New IP Address	New IP Address
213.163.84.159 213.163.84.160 213.163.84.161 213.163.84.162	213.152.168.159 213.152.168.160 213.152.168.161 213.152.168.162

Note: This new IP address will be in effect from 10th October 2011.

We request all Site24x7 users, who use Netherlands monitoring server as one of their primary or secondary monitoring location, to exclude the old IP address and white list the new IP address in their firewall rules. This would enable smooth monitoring of your websites and servers from this location.

If you have any questions, do contact us via support@site24x7.com.

We have added two more locations to our global monitoring network. One server is from Sydney, Australia and the other is from Auckland, New Zealand. Below are their IP address for your reference.

Site24x7 Global Monitoring Network

Sydney, Australia Monitoring Server IP Address	101.0.67.53
Auckland, New Zealand Monitoring Server IP Address	120.138.27.125

In case you plan on using these two new monitoring servers, make sure you white list these IP addresses. This is to ensure smooth and continuous monitoring of your websites and servers from these two new locations.

If you have any questions, send us an email to support@site24x7.com.

We are glad to announce the release of the following new features.

The ability to monitor FTP/SFTP server availability and performance
The ability to monitor the response of round-trip time of FTP/SFTP servers
Comprehensive DNS Analysis tool which provides you with in-depth information of your DNS
Three New Monitoring Locations

New Feature: FTP/SFTP Server Monitoring

The FTP/SFTP Server Monitoring allows you to monitor FTP server's availability and performance. It also tracks the performance of FTP round-trip time (RTT).

FTP Server Monitoring: Monitors FTP Server host availability and performance
FTP RTT Monitoring: Monitors the upload and download response time of FTP service

FTP service is one of the most widely used network protocols by various businesses. It is the simplest way to share information with customers. Hence it is essential for businesses to ensure the availability of mission-critical data to customers at all times. Any undetected downtime can cause loss of revenue in hundreds of thousands of dollars.

FTP/SFTP Monitoring

Site24x7 lets you monitor your FTP server’s host availability and performance from across 30+ global monitoring locations. It instantly alerts you whenever the FTP port becomes unavailable, enabling you to take corrective measures to restore FTP access.

Site24x7 also enables you to monitor the upload and download response time of your FTP server. It uploads/downloads a test file into your server and monitors its response time (time taken by the test file to upload/download). It also works for secure FTP servers (SFTP).

Site24x7 automatically alerts you when,

a) FTP server is unavailable
b) Username/password for the secure FTP server is incorrect
c) Response time crosses specific threshold values
d) File upload and download time crosses your specified threshold.

DNS Analysis Tool:

We have improved our DNS Lookup tool which brings you in-depth details of your DNS in a single snapshot. It gathers the IP address, TTL (Time to Live) and response times of

SOA records
MX records
Reverse and Forward Lookup
Name Server Performance

along with its current status. You can use this tool to run ad hoc tests of your DNS.

DNS Analysis Tool

New Monitoring Locations:

We have now introduced three new monitoring servers – one each in India, Turkey and Israel. The IP address of these three servers is given below for your reference. If you plan on using them, make sure that they are white listed.

Istanbul, Turkey:

46.235.8.142
46.235.8.143

Tel Aviv, Israel:

91.228.126.149

Mumbai, India:

180.149.241.212

You might have also noticed that we have come up with a new design for our website. We have simplified our tab layout with bare essentials and made it easier to access our key website monitoring features. So go ahead and sign up for a free trial and try out our new features. If you have any comments regarding our new features, feel free to share it in our comment section.

We are planning to upgrade our monitoring server in China (Hong Kong). So, if you have IP restriction enabled in your server, you have to reconfigure the new server IP address into the allowed IP list. This is to make sure that our requests come through properly. The new IP address of our server is as follows:

China Monitoring Servers	Old IP Address	New IP Address
Hong Kong Monitoring Server	91.207.192.207	121.54.169.169
