Prod-US Server Migration - Q2 2021

IMPORTANT NOTICE REGARDING NETWORK ADDRESS CHANGES

FOR CORELOGIC CLAIMS (SYMBILITY) – ACTION REQUIRED

As part of our commitment to the highest level of security and performance, CoreLogic will perform a network migration.  Your secure connection to our services will be affected.  Some configuration changes will be required on your part.

The following systems will be included in this maintenance:

• Claims Connect and Mobile Claims
• API and Integrations

Changes will be done in 2 phases:

1. Phase 1 – Move application firewall on Friday April 30th around 9:00pm EDT

2. Phase 2 – Move servers on Saturday May 8 around 1:00am EDT

Our IP addresses will change.

This has a direct effect on your security settings.

Phase 1 – Move application firewall

This phase is currently scheduled to happen Friday April 30^th around 9:00pm EDT.  No downtime is expected.

What this move entails:

• The IP address for www.symbility.net, for downloads.symbility.net and for bi.symbility.net will change from 66.203.104.249 to the following:
  1. 199.83.128.0/21
  2. 198.143.32.0/19
  3. 149.126.72.0/21
  4. 103.28.248.0/22
  5. 45.64.64.0/22
  6. 185.11.124.0/22
  7. 192.230.64.0/18
  8. 107.154.0.0/16
  9. 45.60.0.0/16
  10. 45.223.0.0/16
  11. 2a02:e980::/29

• The ciphers we support will change:
  1. From (current ciphers):
     • TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
     • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
     • TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
     • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
     • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
  2. To (upcoming ciphers):
     • TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
     • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
     • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
     • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
     • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
     • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
     • TLS_RSA_WITH_AES_128_GCM_SHA256
     • TLS_RSA_WITH_AES_256_GCM_SHA384
     • TLS_RSA_WITH_AES_128_CBC_SHA256
     • TLS_RSA_WITH_AES_256_CBC_SHA256
     • TLS_RSA_WITH_AES_128_CBC_SHA
     • TLS_RSA_WITH_AES_256_CBC_SHA
     • TLS_RSA_WITH_CAMELLIA_256_CBC_SHA
     • TLS_RSA_WITH_CAMELLIA_128_CBC_SHA

How does this affect clients:

• Clients who whitelist IP addresses their users can access need to make sure the IP ranges listed above are whitelisted
• Clients who whitelist IP addresses their servers (used for API integration) can access need to make sure the IP ranges listed above are whitelisted
• Clients with older systems used for API integration need to make sure their older systems support one of the ciphers above
• Only very old browsers (before IE 11) and OS’s (like Windows XP) don’t support SNI
• It’s not impossible that clients with older systems used for API integration might have to do something regarding SNI

What’s not affected:

• Our outbound IP address doesn’t change in this phase (it changes in phase 2 below)
• Our services/servers will remain exactly the same after this change (they change in phase 2 below)
• The SMTP servers we use to send emails will stay the same, but a migration is planned in a few of months
• The data export / data dumps SFTP sites used by our customers will stay the same (sftp.symbility.net / no IP address changes), but a migration is planned in a few of months
• https://staging.symbility.net is not affected

Phase 2 – Server Migration

This phase is scheduled to happen Saturday May 8 around 1:00am EDT during our maintenance window.  A downtime of 1 to 2 hours can be expected.

What this move entails:

• The outbound IP address of our APIs will change from 66.203.104.254 to the following:
  1. 34.83.132.80/28
  2. 34.66.126.64/28

How does this affect clients:

• Clients who whitelist IP addresses their servers (used for API integration) can access need to make sure the outbound IP addresses listed above are whitelisted
• The Business Intelligence module will not be running during that weekend and will only be back up the following Monday morning
• The daily data export jobs / data dumps will not be running that weekend and the next files will be generated Monday very early morning

What’s not affected:

• The SMTP servers we use to send emails will stay the same, but a migration is planned in only a couple of months
• The data export / data dumps SFTP sites used by our customers will stay the same (sftp.symbility.net / no IP address changes), but a migration is planned in only a couple of months
• https://staging.symbility.net is not affected

Customer Testing

It is highly recommended that customers confirm their API integration works properly with the new IP addresses and ciphers.

• Customers with accounts on Staging can start testing this today using https://staging2.symbility.net instead of https://staging.symbility.net.
• Customers who also want to test Production can start testing this today using https://www2.symbility.net instead of https://www.symbility.net.

Note that even if the test URLs are used, outbound calls done by Claims Connect will still use our current outbound IP address 66.203.104.254 (for Production).

Also note that the https://staging2.symbility.net and https://www2.symbility.net URLS are for testing purposes only and will eventually be decommissioned.
